I'm having an issue with my Galaxy S2. I typically leave it in Debug mode, up until a few days ago it has worked great. I've successfully loaded APK's for testing through eclipse previously.
I tried to load a prototype of a new app im working on and when I plugged in the S2 nothing happened, Windows didn't beep like usual and when I tried to view running devices it did not show up.
When I look at the device manager under universal serial bus controllers, it doesn't show any 'unknown devices'
I've tried reinstalling drivers through kies, and third party sources (as well as removing all drivers and letting windows install them again for me.
I've tried connecting as Mass Storage Device, with debug mode on and off.
I've restarted both my computer and phone many times.
When my phone is off and plugged in Windows will beep and say that a device was connected but not recognized (which is more then what I get when the phone is on)
And sometimes when I "troubleshoot connection issues" in Kies it will reinstall the drivers and after the process is complete windows will report "Drivers were not successfully installed"
I've tried plugging it into my Windows XP laptop and it will show up as "Unrecognized device" even after I installed Kies on the laptop, and tried the driver installation it with the same results.
Posting here is my last resort as I've spent close to 5 hours troubleshooting this issue, and searching for answers. My biggest concern is that when I do plug my phone in it will beep to say that it is charging, but windows 7 doesnt even see it!
I appreciate all suggestions & help!
EDIT: Also I installed the Samsung Android USB Driver for Windows and windows reports that the drivers were not successfully installed
Thanks

Try to key in dialer:
*#7284#
It has 4 options:
UART
MODEM
PDA
USB
MODEM
PDA
In USB section, select the PDA. If it already selected to PDA then reselect it by selecting MODEM and then PDA again.
Only change the USB setting and then press back and try reconnect to kies again.
Hope it helps..
I had the same problem and JUST as i was about to give up, i realized that I had replaced my usb cord with a generic one from the store. I happened to still have the old one around still and that ended up being my issue -.-; Hope this helps someone else!
This really sucks, I know I've had this happen a few times and it's really annoying to have to deal with. I had luck with this post where they suggest:
... they suggested removing battery from hero with usb pluged in and
then putting battery back in, so i did this thinking it wouldn't work
and hey presto, mounting option became available. I was then able to
follow your first set of intructions to install the drivers through
devices and sync is now working!
If that doesn't work there are a few suggestions and helpful driver websites on there for you to follow :-D
I know I would:
Uninstall all drivers related to your device
Restart Computer without connected
Pull battery on device, plug it in, and once detected put battery back in.
If driver doesn't install correctly, or "unknown device", go to the website on that forum to get the CORRECT driver for your device and Windows OS
Go to Control Panel->Device Manager->(unknown device)->Update Driver
Locate downloaded driver, install
Make sure that when connected, the device says "USB Connected" in it's notification area
Click "Turn on USB storage", or "USB Debugging -> USB debugging"
.. this will at least show you that you have the right drivers.
IF you did all of this and you still can't get it to debug through eclipse, you either have conflicting drivers somehow, or your eclipse IDE isn't setup properly. Maybe update Eclipse, and Android SDK and try again?
Sorry can't give you exact details but this problem could be ANYTHING lol
I had the same problem while using a generic cord.
Don't use for usb transfert
I think they are made only for charging.
Solve by using a stock cord not a generic one.
Okay, so after talking to Samsung they informed me that there is a small defect with the female usb connection, and that it can sometimes be loose.
Only solution, mail it to them...
This fix works on all my computers that "don't recognize" my rooted Samsung Android. Plug the phone into the computer and restart phone. When it comes up again, the computer recognizes it.
My method is KIES AIR.
Open Kies Air
Go to settings > Bluetooth off set.
More settings > Tethering and portable hot spot > Bluetooth tethering check true and portable Wi-Fi hotspot check true.
Now KIES air open on your device and start button click. copy IP address to browser
Your s2 is connected your computer.
Open browser, and copied ip then click paste.
I have two Win XP SP3 workstations that would not connect to my Galaxy. Finally fixed it by installing this particular Intel driver and installing Windows Media Player 11.
if you are running a custom kernel on your phone, you may want to check too if you have "force fast charge" turned on or not. I thought my phone and computer would never talk to each other again but it turned out I had fast charge enabled. Turning that off solved the problem for me.
It might be an issue with USB 3.0 ports. I was tormented by this issue too and I was at the point where I was so ready to burn this device to kingdom come. Before I did that, I decided to use my never-used 2.0 port and guess what, IT WORKED! If your PC doesn't have a 2.0, good luck with that.
punch in code *#7284#, (UART set to PDA) and (USB set to PDA)
solved my problem

I have samsung galaxy note 10.1 and model GT-N8000, I want to connect it to android studio and want to run my own made app. But my android studio not showing anything and even pc do not detect it , not even popping up notification to show me that some thing is connected. I check this device to other computers but got same thing.
So what could be a problem. I have done resetting , but nothing is helpful, Updated driver, installed the google driver for usb, installed the universal driver. But nothing is really helping. So at least pc should detect it but its not.
Any solution. ? Please help
Make sure, that you chose Connect as Camera or PTP on your phone.
Go to developer settings and activate Adb-debugging or USB-debugging.
Also check, whether you have installed the correct drivers. Try to reinstall the correct drivers.
And make sure that neither your USB cable nor your USB-drive is faulty. If so try to use another cable and different usb-drive.
You could also try to connect your phone wirelessly to Android Studio
Couple of things you can try -
Go to settings, developer options and turn USB Debugging on. If it's off, Android Studio will not detect your phone.
If you PC is not detecting your device, either your USB cable is faulty or your USB drive. Only way to know is connect your phone to another USB-Drive or connect it using another cable.
I am trying to connect my android device on mac to test application I developed.
First I installed USB driver, then I activated in my phone the developer option by tapping on Build Number and then tick USB debugging option.
Once I did all those steps when I connect my android mobile, my Mac still not recognize my device.
Any idea to solve it?
Maybe it's your USB cable, try another one.
There are two types of USB cables:
for supplying power only
for supplying power and data
I after few research and testing of existing solutions, I found mine, my issue was released while I have installed Android file Transfer for Mac
I experienced the same problem with a Moto X and my Macbook Pro. I tried many of the suggestions (installed Android File Transfer, tried different usb ports on my computer, Settings => Storage => USB computer connection => toggled between MTP and PTP, etc.). None of these other recommendations helped.
It finally worked when I tried a different micro-usb cable.
Bizarre. You definitely want to first enable Developer Options first by going to Settings => About Phone => tapping Build number 7 times to display Developer Options. From there, you want to enable USB debugging.
I found this solution to be helpful to resolve this problem
Connect your Android to your Mac via USB.
Unlock your Android's screen. ...
Swipe down to open the Android Notification Panel.
Tap the USB option in the Notification Panel.
Tap "File transfer" or "MTP."
Click the Go menu and select "Applications."
Double-click "Android File Transfer."

I had this problem. The only solution was to reboot my computer. Then it started working again.
Just to add my experience here. I had a similar problem with my mac book pro and my Google Pixel 1 device. For me when running adb devices locally, I was no longer showing my device on the list. I would see any emulators I had running, but not my physical device.
My solution and steps:
Go to the "Settings App"
Go to "Developer Options"
Revoke USB debugging Authorizations
Toggle Developer Options off / on
My device then prompted me to allow debugging from my computer and everything continued to work as expected. adb devices resulted in showing my connected device.
Hopefully, this will help someone else if the above does not.
Make sure to have debugging by usb enable on your device.
It is an option inside "Developer options"
I've recently (2018) started to have this issue, and have found the only way to get my device connected is to use a USB hub. I have not been able to track down a root cause but will edit this answer if I can find a solution rather than a workaround.
I connected my Android deceive with my mac:
1) If you use Android studio, you may update to latest version of 1.0.2 or 1.1 preview, because lower version have some problem with ADB connection.
2) You may restart your IDE once again.
3) You may go to settings -- storage -- three docs on the right up corner -- USB computer connection -- enable MTP
I have an HTC U11 and a MacBook Pro (2017). It used to work most of the time, but I experienced issues with it once or twice. Then a restart of the Mac solved the problem.
Recently I was not able to USB debug. adb devices gave nothing, even though my phone said I'm USB debugging (even asked if I wanted to).
After trying many things the solution was to connect my phone and run HTC Sync Manager (I also had to update it). Then it magically started to woek.
I hope it helps somebody.
check your android sdk tools, install your sdk-plateform-tools package.then it is ok
For me what fixed the problem is
i clicked on the notification "USB for file transfer" in the
notification panel on the phone
Clicked on "Transferring images"
Than I clicked on "Transferring files / Android Auto" and it was fixed.
I know this question has been asked numerous times, but none of the threads have had an answer to solve my problem. It seems no matter what i try Eclipse just wont detect my phone, I have set it to debug mode in the settings, i've installed "Kies 3" on my laptop and it says i have the latest drivers already installed on my phone when i try to update it.
I've installed the google USB driver package from the sdk manager and have downloaded and installed the samsung driver from the samsung website. Windows recognizes the device and in the device manager under android phone it appears as "SAMSUNG android ADB Inerface".
Im running windows 7 and have even tried deleting all the mounted dive drivers from regedit as i seen suggested in another thread but still no joy! Really starting to get frustrated with this at this stage i've been trying for two days now to figure this out!
This is such a pain! I need to be able to debug on my phone too as i'm using features that the emulator can't handle (i.e. audio recording). I'm all out of ideas here so any help would really be appreciated!
Thanks
The method I followed to install my GT-I9300 drivers was this:
Download samsung drivers from this link:
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
Then just connect your phone and make sure you have a stable Internet connection: It will download required drivers automatically.
Also, make sure you have enabled Android developer options in your phone settings. Enable USB debugging in developer options.
I usually get it to work, when I switch the USB mode in my smartphone (e.g. MTP to PTP). This way, windows starts downloading more drivers.
1) Try disconnecting device from PC, revoke USB Debug authorization from settings menu, and then re-authorize the computer you are working on once you connect it again.
2) Check to see if you see the phone in DDMS perspective (left hand side) - if so, try clicking on it and it should work.
3) try removing all drivers (Google, Samsung etc.) + scan "leftover" registery entries using a reg cleaning program. Then install ONLY Kies Light version and try again.
4) It once worked for me - try changing the USB cable (preferably, to an original one)
Let us know if something worked!
1) enable USB debugging in your phone's settings.
2) ensure that you have the proper drivers installed.
3) open adb in command prompt and run "adb connect"
I have an android tablet "Galaxy Tab 10.1" and need to connect to my pc to debug but it even doesnt show up on Device Manager when I plug the cable. I saw many solutions and tried it, like:
Downloaded samsung usb driver from here:
http://www.samsung.com/us/support/owners/product/GT-P7510MAYXAB
Also in settings USB debugging is enabled.
But there is still no change! Is there any suggestion?? Thanks in advance!
Go to Settings->Select Storage->Click on the three dots->Usb Computer Connection->Experiment with either MTP or Camera. For my phone it works only with Camera mode.
Well, I changed the cable, reinstalled the drivers and worked :)
After you plugged in try to shutdown and then power on the tablet whilst connected. It solved my issue. Hope this helps!!
You could try turning USB debugging off. Also, is there maybe a setting to change the USB mode in settings? Most Android devices have one somewhere.
I've seen this quite a bit, and it seems that happens when the Samsung connector on the bottom of the device is not properly seated. Remove and firmly re-connect has solved the issue a few times for me.
Disconnecting & rebooting the device, run "adb kill-server", reconnect device, run "adb devices" - seems to solve a good few issues also.
Hi There i got a Simple Solution to share.
1st step: Dont connect your android tablet or phone on the computer in this time. :)
2nd step: if your android tablet or phone is on then TURN IT OFF!!
3rd step: NOW after you turn it OFF turn it ON again then connect to the computer Via USB cable..... SEE IF IT WORKS

Okay Android made this much harder than it needs to be (as usual).
I fought this for two days and finally found a way to turn USB sharing on on the tablet. I loaded the drivers to the computer and it recognized the device but would not read it. The solution was to go to settings, storage and then ignore everything in the storage box. In the top left corner a USB symbol will appear very small next to the sd card logo (if one is mounted) Long Press and drag that down to open a message box. There will be an option to turn on USB sharing.
I've connected my Samsung Galaxy Tab device to my Mac. Yes, I've turned on debugging. When I go to run my application to test on the device the device is not listed on the Android Device Chooser menu. Running the ./adb devices shows no results.
NOTE: Posting this question for others to find. When looking for the solution earlier all I was able to locate were answers to broken links to device driver downloads for Windows.
Make sure you uncheck
Settings > Applications > Unknown Sources (Allow installation of non-Market applications)
Turn on USB Debugging inside Settings > Applications > Developers Settings
If you're trying to connect to a Mac, I had this issue with a Samsung Galaxy Tab 10.1 running Android 4.3. To enable developer options, open the Settings app, tap on "About device" under the "General" tab and then tap on the "Build number" repeatedly (it's grayed out but you can tap on it anyway). A small pop-up will appear showing the amount of additional taps you need to do to turn on these options.
Once enabled, just turn on USB Debugging and it'll show up in Eclipse just fine.
I had this problem on my Mac and after 30 minutes tried switching USB ports and it finally started working on the second port.
I fixed it by reboot the device (Samsung Galaxy Tab2 7.0)
Update your driver for samsung. It can be found here: http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
Connecting your phone after development mode is on, and USB debugging is on.
At connecting to the PC the phone asks to trust this location. Finally.
This fixed my problem while all other tips were incomplete.
It does not answer your question of how to get ADB to see the device - I could not get that working. But what I did to install an APK I needed to test was to put it in Dropbox on my computer, then install it from there on the device.
Connect your device via USB hub instead of directly connecting to one of the usb ports on MAC. It worked that way for me. Please give a try.
There's also a pop-up that comes up at times requesting the currently connected computer to have access to your device(not to be confused with the Linux not supported pop-up; it lies ; ] ). I continued to receive Target:Unknown in Eclipse until I managed to catch it and accept. This is on a Samsung Note 8", which I believe is registered as a Tab 10.1 in my Arch Linux udev rules.
It may also happen that USB debugging is not checked on your device. Please go to developper options in your device and check it is enabled.
By the way, for devices with android Jelly Beam (4.2) and later versions, you will find out that this option is hidden. To activate it, click 7 times on the compilation number, and the option will be activated.
Tried everything, nothing helped. Including
USB debugging enabled
MTP/PTP
ADB restarted
Device/PC restarted
Tried Samsung's USB driver
By tricking/modifying driver installer, installed Google OEM Usb drivers for Galaxy Tab.
All software up-to-date
The only thing that helped is installing Kies3 + setting PTP on device, instantly authorization pops out in device. Everything OK now.
Kies3 download here: http://www.samsung.com/uk/support/usefulsoftware/KIES/
Enable USB Debugging mode solve the problem!
For those who don't know how to enable it (it's very hidden on Android 4.3 onward), see this.
In my case, this solved the problem:
unchecked the Settings->Security->Unknown Sources,
clicked on the upper left corner and changed USB mode from MTP to PTP,
unplugged/plugged the device, and
clicked OK on the USB debugging prompt.
Had this problem last year, never solved it. Again, after googling high and low, I could not find a cure for the USB debugging flakiness. Now for the good news:
1) Root your device. 2) Install adbWireless widget from Play (I am in no way associated with the author).
You are now good to go. After starting adbWireless and following its directions, you can now debug through adb wirelessly to your device, in my case, the original 7" Galaxy Tab.
