Wait for input before reconnecting a Bluetooth device 

On Windows, the Bluetooth device can remain in a connected state if the controller just shut down. It won't return any errors, but it also won't generate any input reports in this state, so wait until we know for sure that the Bluetooth controller is sending data before letting the application know it's available.
