I uninstall all other usb driver, still has problem.
samsung android usb driver, unknow device, usb device disconnect constantly
MTU usb driver, not installed properly.
not sure what is the cause.
=============================================
Updated:
The problem solved by Buy a non-samsung, non-OEM cable.
This this so bad, that samsung OEM cable is the reason of all trouble.
I end up spend $10 buy any brand(except Samsung) cable on amazon.

samsung android usb driver, unknow device, usb device disconnect constantly
MTU usb driver, not installed properly.
Samsung OEM micro usb cable is the ultimate cause, when you move or touch the cable around, it get disconnected, device manger constantly refreshing, constantly scan for hardware change.
Replace Samsung OEM micro usb cable with any other brand will fix all problem.
==========================================================
For my HP Desktop.
1) repeat press F10 when power on, get into BIOS configure.
2) on top menu - advanced - device option - USB 3.0 support (enable it), default is disabled.
3) sometime device manager refresh scan for hardware change, then unknow device,
this is because windows install driver from windows update, should disable it, should let windows install driver from samsung driver folder only,
Disable Searching Windows Update for Device Drivers
Click Start, right-click Computer, and then click Properties.
In the Tasks list, click Advanced System Settings.
On the System Properties dialog box, click the Hardware tab, and then click Windows Update Driver Settings.
Select Never check for drivers when I connect a device.
Click OK twice, and then close the System dialog box.
I believe this is the real cause for all trouble, such as MTU usb driver not installed properly, samsung android device not recognized by PC, android usb device constantly disconnect and reconnect and failed to recognized. etc.....
if you use android simulator, must enable bios vt-x visualation technology from bios
bios - security - system security - visualation technology - enable.

below are try may not be the cause.
=====================================================
try:
1) remove previously installed blue tooth usb device. (or SD card), they may be the problem.
2) remove google androic studio ( maybe problem )
3) unplug internet. ( I see samsung continuing removed add, remove add, not sure if computer keep removing hardware)
=========================
windows, device manager, 'scan for hardware change' constantly , android device disconnect constantly,
Scroll to the right and type 'Power Options' in the search field and click on it.
Click 'Change plan setting' on your chosen plan.
Click 'Change advanced power setting' on your chosen plan.
Find 'USB settings' and open.
Find 'USB selective suspend setting' and change it to disabled.
This fixed ALL my USB 3.0 issues. Not mentioned anywhere else!
Its a BIOS ISSUE. Hopefully your computer has this option.
Go into your BIOS and TURN OFF "Legacy USB Support".
If you want even more speed, (there is a catch), Switch from "quick remove" to Buffering. BUT YOU HAVE TO DISCONNECT THE DRIVE WITH THE REMOVE USB DEVICE OR POWER DOWN THE COMPUTER FIRST.
hey guys here is the fix if you are having trouble with your Windows 8.1 all USB devices keep disconnect / reconnect with power saving off ... this took me two days to try to figure out what the heck was going on so i luckily found the fix hope this saves you alot of time an you dont have to downgrade to windows 7 if you love windows 8.1 good because its not what virgin of windows you have it dosnt matter what OS your on its clearly your BIOS so i suppose many people having this problem has an ASUS motherboard so heres the fix

2.Go into Advanced mode in your BIOS by clicking F7 on keyboard
3.Go to Advanced Tab Scroll down to USB Configuration Scroll down to XHCI Mode yours Will probably be on Smart Auto or Auto so Disable it Completely an Save changes F10 an click yes an exit it will auto restart your computer an BOOM You have Fixed the Problem by simply reading this post Hope this helps guys

my samsung tab s2 and tab pro 8 can't connect to pc windows 7. device manager showing unknow device, device manger constantly refreshing. I try million way, find out Samsung OEM micro usb cable is the problem, I replace it with other brand from best buy, all problem fixed.

I had exactly the same issue, and I think it is related to actual motherboard driver (Windows 8, 10). I have several android devices and all of them are connecting/disconnecting every 1-2 sec.
Things I did:
My BIOS doesn't have any configuration to switch USB 3.0 support
From Power Options USB selective suspend setting set to disabled (didn't fix the issue for me)
In Android dev options change USB configuration to MTP (also didn't fix the issue, as it was automatically switching back to Charging after ~10 attempts to connect)
Fix:
Disconnect all USB devices. (very important as disable operation might not be available)
Open System Properties -> Device Manager
Disable USB Root Hub (USB 3.0)
Disable Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)
Connect your usb devices including android
Enable Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)
Enable USB Root Hub (USB 3.0)
Btw it works fine on windows 7 before it makes updates to motherboard drivers, usually after first updates you can see that usb 3.0 driver support is enabled, and same issue appears.
Hope that will help someone.

Discovered a random weird solution that worked for me (Windows 8.1, Samsung Galaxy A20, Dell Lattitude laptop). The A20 uses a USB-C connector which, supposedly, is non-polarized unlike earlier versions of USB. I flipped the cable over in the phone and the problem went away. Go figure... It probably is a mix of MB hardware, drivers, and who knows what else. Users are on their own as standards evolve.

How to Connect Samsung Galaxy GT-N8000 with android studio

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.

How to use nexus 7 for devlopment with mac os

Im setting eclipse on MacOS 10.8 for android development. My Nexus 7 does not show up in the Android device chooser list. I have an HTC One S and that works fine.
Here are the things i have tried.
enabled developer mode on the nexus
installed all Android SDK extras
tried switching between both MTP and PTP modes on nexus
Installed Android File transfer App on Mac.
There are several versions of this question on SO, most of the answers pertain to windows machines. Note i'm interested in a MacOS solution

I had the same problem & came across this post. For me ono's comment worked. I needed to use a usb data cable - not a usb charge only cable.
See http://answers.yahoo.com/question/index?qid=20130418072711AA6kqOP
For me that happened to be a usb I used to transfer books to my Kindle.
Once I connected the correct usb on the upper left corner the Nexus 7 printed
Connecting as a Camera
USB Debugging Connected
I already had USB debugging enabled and in an attempt to fix this problem I had selected Camera (PTP) instead of Media device (MTP) under the Android Settings - Storage - : (Eclipse) - USB computer connection

Reset ADB by going to the DDMS perspective, look at the devices View and you will see a drop down arrow with one of the options being to "Reset ADB". I'm using the same setup and I have to do this from time to time.
Also, adb seems to be more stable when neither MTP or PTP modes are checked.

Try plugging your Nexus into a USB hub attached to your Mac.
After tearing my hair out for a day, trying every single cable and set of troubleshooting steps I could find online, I found out that if I plug my Nexus 7 into a crappy little USB hub I have kicking around it works PERFECTLY. If I plug it directly into my Mac I get nothing. (Running MacOS Sierra 10.12.5 on a late 2013 Macbook Pro Retina BTW.)

I do not know if this can help you but I see my Nexus 7 tablet in Google Chrome Canary on Mac Os 10.9.1 after doing that:
Installing Chrome Canary on the Mac
- On the nexus 7 : in the settings, click 7 times on the "version" to allow developer mode (not a joke)
In the general settings of your device, the "developer options" items shows up, click on it and in the submenu allow USB debugging
Plug in the USB cable between the device and the mac
- On your device in Chrome Canary: go to "webbdevelopper tools" and allow USB debugging
On the mac, in canary your devices will appear at this adress :
chrome://inspect/#devices
You can inspect the devices with the usual debugging tools (You can open URLs and inspect them) through Chrome Canary.
If I am not clear, the whole procedure is demoed in a video in the course "Web mobile development" at Udacity.
Good luck!

I was struggling with this too. It appears that Nexus 7 devices have an issue with their data pins inside the micro USB slot getting worn out.
My resolution was to
1) blow into the port and try to clean out any dust.
2) i used a small paper clip to pry the data pins up slightly (the inside pins, the 2 outer pins are for power).
This worked for me, as now the data pins in the slot are making contact with the cable pins. Be careful though!

Viewsonic Viewpad 10s not recognised by PC (over USB)

I'm about to start writing some Android applications, I have downloaded Jave/Android and Eclipse.
I have a test Android tablet (Viewsonic Viewpad 10s) which I will be running the software on.
I was hoping to be able to just plug the Android device straight into my PC to allow me to debug/run applications on the tablet.
I have purchased a male->male USB cable and plugged it into both devices, but nothing happens, it doesn't even come up with an 'unknown device' in the 'devices' window. Is there something else I need to be doing to get Windows to recognise this device? (I'm running Windows 7 (64bit)).
Alternatively, is this the best way to be running/debugging on the tablet? I was thinking that there might be a network debugging application, as both devices are on the network?
I'm totally new to Android, so might be missing something obvious. Although I have set the 'USB Debugging' within the 'Development' menu.
Thanks in advance.
Rich.

It's a Windows problem, Windows isn't capable of recognize your tablet on its own, you need to install the appropriate USB drivers for your device in order to use your tablet when it is connected to your PC.
Under a GNU/linux distribution like Ubuntu everything is much more easier and you can just plug in your device without installing anything, you just have to set the right permissions for the device once.

Unplug the device from your machine
Install the driver for your device : http://www.viewsonic.com/support/downloads/drivers/_download/tablet/viewpad10s/ViewPad_10s_USB_driver.zip
Plug your device in
look at the device for a notificaiton saying debugging enabled.
If you dont, you will need to open Device Manager, find the listing that your computer thinks the device is and right click and uninstall it. Then unplug and replug.

Windows won't recognize Galaxy S2 at all

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
Jon

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
