For several weeks, I was able to connect my Nexus 7 2 to my computer running Windows 7, and Eclipse would recognize it, allowing me to run apps on it. The device also showed up when I ran the adb devices command. Every time I plugged the Nexus 7 into the computer, the tablet asked if I wanted to allow USB debugging at that time. (Oddly, it never asked me whether I wanted to always allow it from that computer, but I didn't care.)
I recently updated the tablet to Android 4.4.2. I also updated the Android SDKs through the Android SDK manager. Now, when I plug the tablet in, I do not get prompt about USB debugging on the tablet, and neither Eclipse nor adb can see that it is there.
Here is a list of things I tried to do, gathering ideas from various forums around the web.
Re-download the Asus drivers for the Nexus 7 and update the driver. However, Windows does not even recognize this as the right drivers for this device.
Turn USB Debugging off and on on the tablet, and also revoke all USB debugging permissions.
Change the connection mode from media device to camera
Switch the runtime from Dalvik to ART
Type adb kill-server followed by adb start-server in the command line
Delete eclipse and all the Android SDK and download them all over again
None of this worked. Any other ideas on what to try?
It turns out that the Nexus 7 definitely needs the Google USB Driver. Finding, downloading, and installing this driver worked perfectly.
Because Google's Android OEM drivers page does not include the Nexus 7 in its list of devices that need the Google USB driver, I had been trying the driver from Asus, which did not work. I did not try the Google USB driver because for some reason my SDK manager said it had downloaded the driver, but the driver was not to be found.
Finally I found I could download the Google USB driver from this page, which clarifies that all Google Nexus devices need this driver. Now I have successfully re-connected the tablet to ADB.
I submitted a documentation bug report to Google here in hopes that the OEM drivers page can be updated to reflect that all Google Nexus devices need the Google USB driver.
Nexus 7 tablet with Android 4.4.4. Settings > Storage > USB Computer Condition.
Two checkboxes: MTP and PTP. Uncheck both.
With your phone disconnected
In windows explorer - right click computer, go to manage, in computer management find and uinstall device driver (under Android device)
Download new drivers from http://developer.android.com/sdk/win-usb.html#top
Connect the phone, windows will try to install new drivers, install drivers manually with drivers downloaded as above
The above worked for me
For me, after updating to Android 4.4.2, it was critical that I connected the device as a Camera (PTP) rather than as a Media Device (MTP). Previously, before the update, I was able to connect as a Media Device (MTP).
The problem is that you have not all needed drivers (PC can recognise your phone like usb device but debugging would not work). I solved this problem in Android 4.4.4 by uncheking all items (MTP, PTP, UMS) from menu: storage->USB computer connections and than tick 'Media device(MTP). Now all works fine.
thank you Arthur, I found Nexus 7 tab not working even after unchecking or checking. Problem solved by unchecking USB Debugging (under developer options).. settings>Developer option> USB debugging. then check (put tick the MTP device):.storage->USB computer connections and than tick 'Media device(MTP)
Complete checklist:
Enable debugging onto the device
Select USB Connection as PTP (camera)
Install the driver from http://developer.android.com/sdk/win-usb.html
Before you try anything, make sure you update your Build related tools using your Android SDK Manager. Your adb might be outdated.

I'm trying to test an Android application and have a device connected via USB. The device detects (and charges off) the USB connection but I can't seem to find any record on the computer (running Windows 7) that the device is connected. I looked in Device Manager and did not see an "Android Devices" category, nor did I see an "Other Devices" category. I looked on the device manufacturer's website to see if they had drivers; I could not find any. Does anyone have any idea as to how I could get the device to show on the computer? Thanks!
Most probably windows and especially android adb will see your android device after installing the Google USB Driver
I had the same problem for many of my android devices and most of them are running fine with the driver from google. Only for some sony devices I had to install special drivers.
In Android Studio go to Tools -> Android -> Android Device Monitor. Once it opens close it, this will reset your adb and you should be able to see your device
Your problem sounds related with drivers
the Google USB Driver works only for some android models, some other drivers are installed as plug and play but some others you have to install manually.
http://developer.android.com/intl/es/tools/extras/oem-usb.html
Also sometimes it happened to me that the adb didn't recognize the device while the screen was locked so you could also check that out.
It turned out that the USB cable I was using was a charge-only cable. After switching the cable out, the device showed on ADB.
Android Studio 0.3.6
Fedora 18 3.11.7-100.fc18.x86_64
Nexus 5 Kitkat
Hello,
I have been using my Samsung Galaxy Tab 3 7.0 running Android 4.1.2 everything works fine with adb.
However, I have just bought a new Nexus 5 device, and when I do the following command adb devices it doesn't show my Nexus 5.
Under Android SDK Manager | Extras | Google USB Driver | status "Not compatiable with Linux"
Because I am running Fedora 18 if I need drivers what drivers for the USB do I need?
Because the Samsung works fine and I can deploy and run my apps, I think my setup is correct. So I am wondering if there is something wrong with my Nexus 5.
I have tried the following:
adb kill-server
adb start-server
Setting the Nexus 5 Camera PTP and media device MTP didn't work.
Many thanks for any suggestions,
I had a similar problem with my Nexus 4(Android version 4.4.2), it wasn't listed in adb devices.
Make sure USB debugging is enabled from device, and do the following on your PC:
Update Android SDK (Google USB Driver)
From PC Control Panel, System -> Device manager -> Right click Nexus 4 -> Update driver.
Set android-sdk-folder\extras\google\usb_driver as path to search, include subfolders checked.
If windows tells you that the driver is up to date, just uninstall the driver (right click on nexu4 -> uninstall driver) and start from step 2 again.
After that, open a cmd and type adb kill-server and then a adb devices, now it will include your device.
https://developer.android.com/studio/run/oem-usb.html
Follow these steps,
Enable Developer options in your device. To enable the developer mode, Settings->About phone, tap Build number option 7 times continuously
Go to Settings-> Developer options and Turn on USB debugging
Make sure you reconnected the device via USB and grant permission on the dialog that appears.
From the above steps it didn't work try this step, Go to Settings->Security and turn on Unknown Sources
What you need to do is this:
Settings | About Phone
Scroll to the bottom to build number.
Tap on build number about 7 times. Each time you will get a popup message saying you are x steps away from being a developer
When you get to the final step you will get a message saying now you are a developer
Go back into settings and you will see a new setting Developer options there you will see a lot of options for developers. Enable USB debugging
Re-connect you phone to the usb, and you should see you device under adb devices.
I hope this answer helps someone else.
This simple steps worked for me, I debug on my Nexus 5 and 5X devices on Windows 8.1.
The steps to follow are these:
1) Enable from Developers Options the Debug USB Mode
2) Unplug the device from the computer
3.1) Go to Settings → Storage, in the ActionBar, click the option menu and choose USB computer connection.
3.2) If you didn't find the 3.1) option then go to Settings → Developers Options → Select USB Configuration.
4) Select Camera (PTP) connection.
5) Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection, or something like that.
6) If it doesn't work try to toggle the Debug USB Mode in the Developers Options
Finally, you should see it now in the DDMS and voilà.
My windows solution:
Go here and download and unzip to an easy location:
http://developer.android.com/sdk/win-usb.html#top
Right click 'My Computer' or 'Computer'
Select properties
Select Device manager
Look for your device. It should have a yellow mark above it.
Click 'update driver software'.
select browse my computer for driver software.
select the usb_driver folder you saved earlier.
install it
and wala. magic.
For those who are still frustrated, if you are using the experimental ART runtime, try switching back to dalvik (in developer options on device)
Here is simple solution for Windows 7 and Nexus 5 on Android 5.
Download the Nexus 5 Drivers from http://androidhost.org/jelry
Extract the zip contents and place all files in a single folder on your desktop.
Connect your device to your computer.
Launch the Device Manager on your PC.
Now you should see the Nexus 5 listed in the hardware list.
Right-click the ‘Nexus 5′ line and then click on Update Driver Software.
Next, click the ‘browse my computer’ option.
In the new window click on ‘Browse…’ button.
Go to folder unzipped at step 2. Select the folder where you extract the USB Drivers. Click Next. – make sure to tick the subfolder box too.
Now, the Windows installer will search for Nexus 5 drivers, click Install when asked for permission.
Wait for the process to complete and then check the Device Manager list to confirm that the installation was successful.

Note: do not forget to enable USB debugging on your device :)
Something nobody has mentioned yet:
Some cables do NOT support data. I was sitting here wondering why my Nexus 5 was refusing to show up on OSX. It turned out I was using a cable that didn't support data.
I swapped to a different cable which did support it, and suddenly I was able to use USB debugging.
If anyone is trying to connect Nexus 5 to a formatted Windows XP then follow these steps:
Download and install media transfer protocol porting kit:
MTP porting kit
Download and install WMFDistributable-11 for XP:
WMFDist-11 XP
Download and install LG United Mobile Driver v3.10.1:
stackoverflow is not allowing to share more than 2 links, please google this.
Connect your device.
Go to Device Management
Right click on Nexus 5 and click Update Driver
Select Yes this time only
Select Install Software Automatically
Wait for sometime.. and enjoy transferring files
ADB and driver versions matter. The newer the device, the lower the chances of an older version ADB to work correctly.
Apps using their own ADB copy need to be updated or at least have their ADB updated manually.
When installing Helium / Carbon for instance, it uses an old / incomplete ADB. Newer devices might not link to the ADB server for this very reason.
What I'm writing here should work for any future devices on Windows and possibly *nix OSes.
First the systems must be prepared.
on Android:
activate developer mode, either from an app (like Helium, when prompted) or by accessing the about phone section, taping build number until the developer mode unlocks
in developer settings enable USB debugging
in security settings allow unknown sources
(when connected with USB cable) set USB connectivity to PTP mode (camera device, if so labeled)
in Windows:
uninstall older USB driver (with file removal) if there is one, but only when the device is connected and in developer mode, otherwise
that particular device won't be listed
install latest USB driver after the device has been plugged in and developer mode is active, the device will be listed as unknown or other in Device Manager; the drivers can be downloaded separately from Google Android support site, these are the same as vendor drivers, with only fewer ID's in inf file making the driver not being recognized for all Android devices
if the driver does not recognise the device, no problem, install it generically: Manual Install > Show All Devices > Have Disk > pick inf location of the Android USB driver and from the list select Android ADB Interface; there's not need to edit the inf by adding hardware ids, the end result is the same
each of the modes, PTP and MTP will have their own driver entry, so if the device asks for MTP, the same driver installation procedure must be followed, again
Once these steps are/were previously done correctly, adb must be tested.
If Android SDK was installed previously, open a command prompt where adb.exe is
and test the listing of the device.
adb start-server
IMPORTANT NOTE: This command will prompt the device to allow the communication between the computer it's been linked to on the first run. The prompt will also list an RSA key specific to the PC in question. Without this prompt on start-server, ADB will NOT work! Nor will any application relying on ADB.
adb devices
Must list the device(s). If the list is empty, and most likely the RSA prompt did not occur, then no communication will work. If the list is empty the current ADB (and SDK) must be updated or installed fresh (in the case of apps bringing in their own ADB runtime, like Helium / Carbon).
In the case of applications that do bring their own ADB, if the version is old, and these apps insist in using it instead of the SDK one, these files need to be replaced with the latest ones from Android SDK. Plain and simple copy & paste.
As for Android SDK, the only required packages to be installed are SDK Tools and Platform-tools. There, ADB.exe will need some support libraries, on Windows these files are AdbWinApi.dll and AdbWinUsbApi.dll. After all is done, the SDK can be uninstalled from SDK Manager while being able to retain the ADB tool if this is the only runtime used, depending on the case in question.
After doing all steps like enable debug, ... I had to put a sim card and reboot the phone
Solution for Windows 7 and Nexus 5 (should be applicable for any Nexus device):
I figured out that my system was installing the Nexus 5 default driver for windows automatically the moment I was connecting my Nexus 5 to my system through USB. So uninstalling the default driver was in vain and it gets installed automatically anyways.Moreover if you uninstall the default driver, you won't be able to locate Nexus 5 under Devices in Computer Management. So here is what i did and worked for me!
Computer-->right Click-->Manage-->Device Manager-->Portable Device-->Nexus 5-->Update Driver Software
Choose 'Browse my computer for driver software'
1.Make sure to give this location: %APPDATA%\Local\Android\sdk\extras\google\usb_driver
Click Next and you are done.
I have suffered the same issue and was able to solve it by simply changing on my Android device (Nexus 5X) in Developer options > Select USB Configuration to RNDIS (USB Ethernet)
For those trying to connect their android phone in adb with no luck and have tried every USB configuration (MTP, PTP, RNDIS). It is worthing noting that in my case with my Nexus 5X on Windows 7 I successfully connected the phone to adb only by choosing the Charging USB Configuration. With any other configuration (MTP, PTP, ...) it doesn't work.
USB Driver: Google USB Driver v11
ADB Version: Android Debug Bridge version 1.0.39
Madx's answer is a strong hint. Now I can make MTP work for my Ubuntu 20 and Nexus 5X (Android 8) device. MTP is an easy solution in Windows for smartphone users. However, to me and many Ubuntu/Linux users, current Ubuntu/Linux MTP tools "LOOK" messy and unstable for Android devices, e.g. No folder is shown for android phone in Nautilus.
Delving deeper I find it might be a security enhancement done by GOOGLE in the Android device/phone side. Direct internal data access remains a privilege for the developers. And one needs to set/reset MTP as a developer for Android device in order to make Ubuntu MTP tools work. There is nothing wrong with Ubuntu/Linux MTP tools.
The steps for MTP data access are an extension to Madx's answer:
(For Android device) Enable from Developers Options the Debug USB Mode.
Unplug the device from the computer.
3.1) Go to Settings → Storage, in the ActionBar, click the option menu and choose USB computer connection.
3.2) If you didn't find the 3.1) option then go to Settings → Developers Options → Select USB Configuration.
4.1) Select MTP connection.
4.2) Select Camera (PTP) connection.
4.3) Select MTP connection again. (This refreshs GOOGLE MTP protocol stack, I guess)
Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection, or something like that.
If it doesn't work try to toggle the Debug USB Mode in the Developers Options
And now file folders are shown up for N5X device in Nautilus.
Are these too much? There might be a bug in Android MTP implementation, and 4.2) & 4.3) are steps to WAKE Up Android MTP stack:-)
As a kind reminder, Windows and FTP are the last resorts for MTP.
Try executing :
sudo ./adb kill-server
sudo ./adb start-server
sudo ./adb devices
In my case:
The phone was connected as a media device.
Clicked on that message and got a menu. "USB computer connection"
In that menu chose to connect it as a camera (for devices that do not support MTP)
And then it worked.
Oh boy, I spent 3 hours for this simple thing and tried combination of above instructions.If it doesnt work for you, just try several combinations of above instructions and it will. I am on windows 7 and nexus 5. Issue I had was when I try to install driver from the google usb folder, windows 7 fails to install. Here are my steps:
-first uninstall all nexus drivers on windows 7. connect with USB cable, go to device manager and uninstall the driver; unplug the cable and repeat until no drivers are found and nexus shows up under "other devices" in device manager. I also configured nexus device as camera (PTP)
-follow #Dharani Kumar instructions. They make appropriate configuration changes for nexus device
-follow #Harshit Rathi instructions. They will ensure eclipse can show the device when windows detects the device
-unplug and replug the USB cable after a minute. Now you should see a pop up on nexus device. click it so that windows 7 will allow installing the driver from your local system. if you dont see this, restart your device or pc
-follow #Rick's instructions.you can download USB driver as listed by #jimbob
If you still have a problem, re read this entire thread and go from there (I spent hours on other web sites; those bits and pieces didnt help)
Go here and download and unzip to an easy location:
http://developer.android.com/sdk/win-usb.html#top
Download and install
I had the same problem, USB debugging enabled, device showing up in windows but I never got the question about RSA fingerprint when I connected my Nexus (6) device, nor did it show up in the Android Device Manager.
BUT
In the windows device manager I did have an entry saying it was an android device and Composite ADB interface etc. Still didn't work.
When I tried the previous tips about manually updating the drivers, Windows 8.1 just responded that "Windows has determined that the driver software for your device is up to date" this was not true. Looking at the driver details I saw that the driver was published by "ClockworkMod". I realized this must be because I had installed the Helium app sometime last year. So I uninstalled that, still had the same problem. Checked again, this time it was indeed google drivers, but version 7 published in 2012 (and not version 11 published 2014). I uninstalled these AS WELL and then tried the trick of reinstalling the driver from the SDK located in:
%localappdata%\Android\sdk\extras\google\usb_driver
Now when I replugged my device it finally works and can be debugged with Android Studio.
Indeed a driver problem.
Answer by Rick and MadX is the right way to do the steps (Thumbs Up for the answer)
In my case I am using
Akcess USB Type C Data Sync Cable For Nexus 5x, 5P - White
As Nexus 5x do not supply type C to usb cable I purchased it from some vendor.
Having the same issue. What I am doing stupidly is:-
I am connecting the cable in wrong way. After I reconnect it from upside down its working for me.
I might think that some of the Cables do not support debuggable. But its in my case.
This(Image) is my case the Type C should be as USB side symbol. A stupid solution, but work for me
I have a Samsung Galaxy S4 that I would like to deploy my app to using eclipse. However the device simply does not appear on the list of devices to deploy to.
I am using Windows 7 64-bit.
The phone appears as a drive when plugged in, allowing me to transfer files to and from the device.
The phone has developer mode and USB debugging switched on.
In the Android SDK Manager, the Google USB Driver appears as installed.
I have manually installed the usb driver located at \extras\google\usb_driver\.
This same device has been recognised and deployed to on other computers.
I have tried restarting the adb server in command prompt using adb kill-server and then typing adb start-server.
I have tried restarting both the phone and the computer.
My deployment screen simply thinks there is no android device:
Any ideas? Is there perhaps something I am missing here that is required for my android device to be properly recognised by eclipse?
First, is your device id showing up when you use adb devices
If it is, it's just a matter of restarting eclipse. Another cause could be that you're using the Google USB driver, whereas you should be using Samsung's Android USB driver, which can be found here:
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
Get the drivers for your Galaxy S4 here:
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
P.S. ya better got Nexus 5
You should install Samsung KIES, that have included some USB Drivers and something more, then you will able the possibility to eclipse sdk recognize your Phone, i was with the same problem, after i installed KIES everything worked fine, trust me.
KIES Download:
http://www.samsung.com/us/kies/
I have tried every suggestion on this website and many others to no avail. Is it even possible to do android development for a nexus 7 on windows?
I have tried the usb driver downloaded from the sdk manager, the one from asus. I have tried changing the usb mode to PTP and I am still getting the the same message when I try to install the driver (manually).
"Windows could not find driver software for your device"
I know this question has been answered, but I just ran into an issue where uninstalling the Unknown Device, and then updating the driver manually was not working (by selecting the sdk/../usb_drivers folder). No matter what I did from Device Manager, I could not get the drivers to be found/installed.
Hopefully this helps someone - if you have an issue installing the device (Win7), this worked for me:
Disconnect the USB from the device.
On the device, go to Settings -> Developer Options, and click Revoke USB debugging authorizations.
On the device, go to Settings -> Storage -> USB Computer Connection (available on the drop down menu at the top right of your screen). Verify that Media device (MTP) is CHECKED.
Reconnect the device, and it should install successfully without a problem. If not, attempt to update the driver manually and point Windows to the usb_drivers folder of your SDK.
I just had this problem occur for me with two factory new Nexus devices (Nexus 7 and Nexus 4). For both devices, I had to do the steps above and everything worked fine afterward.
Ok here's something awesome. When browsing for the driver DO NOT select the architecture (i.e. amd64 or i386). Just browse to the "usb_driver" folder. It is working now.
\your_sdk_path\android-sdk\extras\google\usb_driver
I had to hook up 4 Nexus 7s (2012) on Windows 7.
After much trials, tribulations and many errors, here is what I had to do, for EACH device.
Plug in the Nexus 7 using USB. Watch it fail to install one out of 4 drivers.
Now, Computer -> Manage -> Device Manager -> Right Click on device -> Uninstall
NOTE: Check "Delete the driver software...". This buys you some time
-> OK
Unplug USB, wait 5 secs, plug it back in.
Windows tries to install a driver.
BEFORE it can complete, Right click on the device that appeared in the device list
and select "Update driver software"
Gotta be fast here. Time is of the essence. If you are slow, delete and repeat.
Browse to the Google driver ( \extras\google\usb_driver ) -> OK
Try connecting via Eclipse..
For me, at this point, the stupid Nexus was asking whether to accept a key.
Say OK, and I was all set. Not fun...
I have a new nexus 7 with 4.4. Had to "enable usb debugging mode" specifically in developer options.
Haven't seen this mentioned previously. Everything seems to work fine after that.
Here is a guideline how to install nexus 7 driver in windows: http://developer.android.com/tools/extras/oem-usb.html
I was also facing same type of problems and following this guideline my problem was resolved.
In a nutshell:
open SDK manager and install Google USB Driver
then manually update your device driver from Device Manager(control panel>>other devices)
Install the driver manually through device manager of your PC.
Try following these instructions: http://developer.android.com/tools/extras/oem-usb.html I couldn't get it working but after installing them manually it worked just fine.
Windows installs different set of drivers depending on whether you have USB Debugging enabled or disabled in Settings -> Developer Options (Of course, if your device is not rooted, you don't have to worry about USB Debugging as you won't see the Developer Options).
So unlike Lo-Tan suggested above, it is NOT required to disable USB Debugging.
I would rather install the drivers in 2 steps:
- First have the USB Debugging enabled and manually update the drivers.
- Second, disconnect the device, enable the USB Debugging and again manually update the drivers.
As Lo-Tan suggest, it is required to have MTP Enabled as explained in point number 2.
I was having issues with the latest adb usb drivers on my 2012 nexus 7. I installed an older version from this link and they worked. https://app.box.com/s/2c25e8bc42ecce400afd
Nexus 7 2013:
When changing mode and looking at device manager:
MTP: i see only the "Nexus 7" device under "Portable Devices", not updatable
PTP: i see "Nexus 7" under both "Portable Devices" and "Other devices"
none: i see only "unknown device" under "Other devices", not updatable
So, to fully install drivers, with adb interface, i had to put it first into PTP mode (+debubbing mode).
Then update the drivers of the nexus 7 device under "other devices" manually with the google drivers.
Now put the tablet in MTP mode and update the nexus 7 driver under "portable devices". choose "let me pick...", then "composite..".
The "Android Composite ADB Interface" now appear under "Android Device".
et voila..
I found that when installing either the Asus or Google OEM drivers it didn't install. But when updating the driver from device manager choosing "pick from list" and select Google as the manufacturer and select "Android ADB Interface Version 10.0.0.0" (after installing the Google USB Driver)
Notably this is on Server 2012 (albeit more similar to Win 8), but the same might apply to Win 7.
Just in case you have Windows 7 edition N:
Windows 7 N edition is a release of Windows 7 distributed in Europe that lacks the Media Center/Player parafernalia, so that the users can choose their own. Windows 7 N does not include the drivers for the Nexus 7. The Nexus N drivers "suddenly appear" when you install the Media Feature Pack for Windows 7 N and Windows 7 KN. Otherwise it is difficult to make the Nexus 7 connect through USB. After the upgrade, it recognizes the Nexus 7 automatically by plug-&-play.
My Nexus 7 2013 worked fine connected to my laptop for months. Then yesterday I couldn't get it to be seen by the debugger. I tried every thing on this page with no luck. I especially like the driver installation guide in the Nexus Root Toolkit (NRT) and USBDeview, but no luck. NRT's driver installation guide has step by step instructions that are great for debugging these types of Nexus driver issues. I highly recommend it.
Today, it is working fine again.
The difference? Yesterday, I was in my office and my laptop was docked in a docking station that has built in USB hubs. Today, my laptop is undocked and there is no USB hub. Both days I was connecting my Nexus to the same USB port, and while I couldn't get my laptop to see my Nexus, my Motorola and Samsung devices were fine.
I don't know why this makes a difference, but if you are stuck with this problem, try removing any USB hubs and/or undocking your laptop.

ADB dosn't recognize my Galaxy Nexus - Win7
I'm not seeing my Nexus7 listed in Eclipse's DDMS Devices.
DDMS and "adb devices" from the console show my G1 android phone, but not the Nexus7.
Usb Debugging is enabled on both phones, Eclipse is up to date as far as I can tell, Android SDK's Google-USB-rev6
When I plugged in the N7 USB, I did see the Windows7 driver installed, and can browse files on it from file manager.
MTP/PTP made no difference (MTP drivers from Microsoft Update, none for PTP)
"Select debug app" in Developer Options shows nothing.
"Unknown sources" is checked.
Tried different Usb port, toggled Usb Debugging.
Heres what I did to get it working:
I happened to already have ADB drivers for the Samsung Galaxy Nexus installed, if you don't, you need to download those.
Plug in the Nexus 7 and windows will find 2 drivers automatically, but won't find any for "Nexus"
Go to Device Manager, under "Other Devices" you'll see "Nexus" with the yellow exclamation mark, Right Click>Upate Drivers>Let me choose>Let me pick form device drivers on my computer.
Scroll down to "SAMSUNG Android Phone" (Again, the Galaxy Nexus drivers should be installed already, if not, find them), and choose the driver for "Android ADB Interface"
Click "Next", and the device should pop up in Eclipse.
It worked for me, at least.
This is how I finally got it to work.
Download the naked adb driver:
http://forum.xda-developers.com/showthread.php?t=1766220
Unzip it
Open device manager
Find Nexus 7 in portable devices
Right click and select Update Driver Software
A couple clicks and typing lets you enter a path for your driver, enter wherever you put the unzipped naked driver
Now when the device is plugged in it shows up as Android Phone which seems like we are getting somewhere.
Reboot (I got frustrated because still not seeing my device in ADB DEVICES--might not be necessary)
Device manager, right click Android Phone/Google Nexus 7 ADB Interface, Update Driver Software
I selected USB Composite device but don't remember exactly how since I can't get back to that screen
ADB DEVICES shows my device now! (Also Eclipse)
When I go into Device Manager the driver for my nexus 7 is "Google Nexus 7 ADB Interface" provided by Google, Inc., dated 12/6/2010, version 4.0.0.0 and it is not digitally signed
Hope this helps someone, why doesn't ASUS have a downloadable driver on their website?
I wasted a bit of time getting my Nexus 7 USB/debug connection to work. In between poor documentation and lack of feedback from Windows 7 drivers, I missed a subtlety in the setup on the device. Enabling the debugging features on the device proper is actually two modifications, not one:
Go to Settings -> Developer options
Enable the developer settings overall by toggling the button on the top right, which enables other settings on the page. I skim read the rest of the options, and figured I was done.
Then enable the option "USB debugging", subtitled "Debug mode when USB is connected". If you don't switch this on, your drivers will register, but never do anything, or tell you why not... i.e. you're device won't even be listed when you run "adb devices", and Windows won't enable any of the standard USB file access features either.
Are you using a 32-bit or 64-bit version of Windows? I too have the same problem and have had success using the same device on Macintosh.
My experience with drivers and 64-bit windows has been hit or miss since the Nexus One.
The correct driver now appears to install to [Android SDK]\google-usb_driver instead of just usb_driver. I still have both directories but once I pointed the driver update at the Google one it worked.
Use a mac?
I have the same exact problem and have spent hours trying to get this to work on my Windows 7 laptop, I have messed around with the Universal Naked Driver (0.7) and tried to use the driver install tool in the Nexus Root Toolkit (1.5.2). No help. I also searched Asus for a driver (nothing but a manual there). I also made sure all my Android SDK software was up to date.
When I try on a Mac it does show up! It still doesn't show up on my Windows 7 laptop using "adb devices", or in Eclipsed under DDMS. A galaxy nexus running jelly bean shows up just fine on the laptop.

The Samsung Galaxy Nexus phone that works is using a Samsung driver
Got it working by downloading and running the root toolkit from (http://forum.xda-developers.com/showthread.php?t=1766475), just far enough to put the Nexus7 drivers in a directory I could point to, and "Update Driver" for the "MTP device" manually. Similar to what user1023127 did below with Samsung-Nexus drivers, but I didn't test those.
Now seeing asus-nexus device in Eclips/DDMS, and was able to run an app on the tablet.
I can confirm HappyFunBall's solution. Do not use the automatic driver install in Nexus Root Toolkit; complete Step 4 of the manual install and stop.
I don't think you need drivers.
Do what I do:
Publish your app to your computer.
Then In google play download Bluetooth File Transfer app (or any other file manager).
Copy your app to a folder inside your nexus 7.
Open Bluetooth File Transfer and click on your app.
And finally click ok to install.
You'll have to do this until Asus releases some User Friendly Interface.
