Make sure your device is connected to the computer and run adb device in command prompt (you may have to browse to &lt;Android-SDK&gt;/platform-tools. See if adb displays your device. If it doesn't, go to Settings > Developer Settings  and select Revoke USB debugging authorizations. Disconnect and reconnect your phone and authorize it to be debugged through the computer.
