ok, i have PS2 dance pad, i know its compatible with stepmania. I plugged into a PS2 -> USB convertor, plugged into a usb -> xbox convertor. it doesnt work in stepmaniax on the xbox. i try a keyboard in XBMC and it works fine. the keyboard doesnt work in stepmaniax, though. is there something specific i have to do to get either my keyboard or dance pad to work. i tried in stepmaniax_v12 and stepmania 3.9.
