adb android devices list randomly empty

Question

I am developping an android application and I am having trouble getting adb to work reliably. Every now and then, my device (Samsung Galaxy S6) does not show in adb devices list anymore.

I have tried all solutions others suggested (restarting adb, restarting the device...), but none of them worked. Also, I seem to be the only one whose device is only sometimes not recognized.

I am using adb on ubuntu 14.04.

Any ideas ?

Answer 1

I see you found your solution, but for other's where this continues I had the same problem, until I simply 1. ran

adb wait-for-device

2. reconnected the device via usb
3. changed "Use USB for" "File Transfers"

Answer 2

I just found out the problem was related to Chromium device inspector (chrome://inspect/#devices). Just closing the tab and reopening it did the trick. I'm using Chromium 45.0.2454.101. It was really driving me crazy ! Hopefully it spares someone else the trouble :)
