During development on an app, i plug in the nexus 7 in my ubuntu and mac. The USB Debugging icon on the notifications always connected/disconnected and vice versa. How do i keep this from happening and displays always in debugging mode?

i attempt to fix it by these steps:

  • restarted adb
  • rebooted device
  • revoke usb debugging authorization

tried all of these but nothing happens.


Check your USB cable it must be lose.

  • it isn't. i've been using this right from the day i bought it since the release of 4.2 and had no issues on usb debugging – chip Mar 3 '14 at 6:03
