I was testing new Android Run Time (ART), but after that I can't use USB debugging. After that I had changed runtime back do Dalvik and factory reset phone with no success? I also have updated drivers.

I was checking drivers under Computer -> Manage -> Devices but always got message that my drivers are up to date.

Here is solution:

Eclipse -> Android SDK Manager -> Install updates (Google USB Driver)

NOTE: Before you start installation save Eclipse projects and exit Eclipse.

  1. Enter dos or shell,try using command "adb connect usb" or "adb restart"
  2. If the step above dose not work,try using WIFI to debug.Download a adb test app named ADBDEBUG or else，then enter shell,use "adb connect ip:port".
  3. Maybe it's useful for you.
