You have to check if your device is authorized: adb devices

If its not authorized then that helped me:

  1. Disconnect USB between PC and device
  2. Stop adb server by entering "adb kill-server" in command window
  3. On device use "Revoke USB debugging authorizations" in "Developer Options"
  4. Reconnect the device to the PC
  5. Open a command window and enter "adb devices". Watch the device's screen for any Authorization message and allow the connection.
