I use "adb devices" to get following result. Only one device is connected to PC by USB, but we get 8 lines of result.

Could anyone suggest the reason?

Try the following:

  1. Unplug the usb and plug it back again.

  2. Go to the Settings -> Applications -> Development of your device and uncheck the USB debugging mode and then check it back again.

  3. Restart the adb on your PC. adb kill-server and then adb start-server

  4. Restart your device and try again.
