The plan is to support HID devices to get rid of the PS/2 keyboard interface.
Also, supporting USB gamepads instead of or in addition to 9pin Atari/Commodore style joysticks would be cool.
Supporting USB mass storage would be really cool, too. And USB hub support, so mass storage and HID devices can be connected simultaneously.
But for now, I have no clue how USB works and how to use the MAX3421E, so let's take things one at a time..
