After upgrading to Android Studio 2.2, adb will disconnect from my devices after a few minutes (~ 15 mins). I have to either re plug the device or disable ADB and renable every time. It happens with all devices. This is on MacOS Sierra. Is there a timeout setting they have added?

I ran into this error as well, and it turned out that the problem for me was that a Stetho tab was open in Chrome (i.e. a tab at URL chrome://inspect/#devices ), which I guess was causing the device to be in use. Closing that tab, then running adb kill-server, made adb devices work again.

The issue is with ADB and it is reported in the bug tracker: Issue 219085: adb does not work reliably on MacOS Sierra.
Answer from the thread:
The fix has been released in the Beta Preview Channel, we apologize for the inconvenience.or more information on how to use the Beta Preview Channel, please consult http://tools.android.com/download/studio
Edit-1:
Upgrading 2.2 to 2.2.1 or uninstalling the Android Studio-2.2 and installing the 2.2.1 won't work. Try to do clean uninstall by following the thread How to completely uninstall Android Studio? and check.

I think this it, I think I actually upgraded Android studio after Sierrra, or the problem started happening after upgrading to Sierra. – Steve M Oct 09 '16 at 19:49

Try to install the drivers again and restart the Mac, it works for me on AS 2.2

if you do not want to upgrade your Android studio to preview version , just open the sdk manager and upgrade the sdk build-tools, then restart android studio . it works for me !
