Scancodes are pretty freaky, since there are 3 different sets used over PS/2 and a single defined set over USB. Since this is supposed to be a seriously connected device, and not every machine accepts the USB standard (or even anything besides Set 1...), I'll need to include all of them into the device and give it either (preferably) a way to differentiate its connection or (less preferably) manually set which set to use. Should be loads of fun!
