Can't use USB debugging after ART

Question

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.

Answer 1

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.

Answer 2

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".
