I have a driver written and ready for testing for LucasChess, Shredder and Arena on Windows. Unfortunately my board was one of the ones that suffered from the dead power supply/low battery problem so I am having to wait for the second batch of boards.

I'm guessing I won't be able to release my driver until sometime in May, but Chessnut have used some technology I haven't had on other boards (USB HID) so it might be interesting and might take longer. The BLE connection should be OK though.
