Under failure conditions of the GC Adapter, When interface count is zero and we can't open the device.
Then there were race conditions on shutdown of the threads which could result in crashing.
Make adapter opening more robust like the Mayflash DolphinBar.
Make shutdown more robust by making the read thread control the write thread.
Make sure that there is actual data to be written when kicking the write thread. So it doesn't attempt a write a shutdown.
Make a toast on screen to tell the user that the adapter needs to be unplugged and plugged back in again for it to work.
No way to properly enable it from an end user perspective yet.
Doesn't require root.
This same sort of system can be used for the Dolphinbar in the future for real wiimote support.
