About using IOIO card with NOOK...

For me it works best like this:
Power of the NOOK & IOIO card
Power on the NOOK and IOIO card, USB cable connected
Start TopHat. When you get a black screen with warnings,
disconnect USB cable, and wait..
Once SD card detected and TopHat start screen opened,
reconnect USB cable
Start TopHat in FLY mode

Have not tested with XCSoar yet, but the new 6.7 beta looks very
good. Will test tomorrow...
