We used Mouse devices which where re-soldered to use the 4 USB wires as 'short to GND' to work as controllers.
That is, each button got explicitly one of the Din, Dout, Vcc wires and shorts it to the GND wire of USB.
USB plugs where of course snipped off.
We also did re-solder some of the existing capacitors of the USB-logic board and put them in parallel to the
switch to suppress electric bouncing of the switch signal.
