adb.exe has stopped working, Nexus 7 not detected over USB

Question

I'm using Google Nexus 7 to debug an applications. but now it is prompting the error message below and and popup is coming stating that the USB device is not recognized. But it was working properly a few days back.

I have not made any updates on the device or the Android SDK.

adb stopped:

USB device not recognized:

What's wrong?

Answer 1

Sometimes the adb executable,is executed several times causing this error, check on your Task Manager (not sure how it's named).

Kill all of them, and restart the adb by taping this command "adb devices" on any windows shell (cmd.exe or powershell).

Hope it'll help you :)

Answer 2

It happened to me during debug, I just unplugged and plugged back the USB cable and adb return to work just fine.

Answer 3

this question is about the adb server version in local machine doesn't match with the adb under the C:\Users\Administrator\AppData\Local\Android\Sdk\platform-tools; find a same version of abd.exe copy to, then run, done well i tried to find the key and resolve.
