Greg - Robofocus is probably the most adaptable for this purpose

H - I converted all my Robofocus controllers to native USB.

Got a mate to do the first ones.
You have to add another chip (a Max232) into the design and a couple of diodes to prevent power from back feeding from the USB power though the chip and back into your motor controller if the power drops out (learnt that the hard way !)
Its not hard - not sure if I still have the circuit diagram though.

Bojan could do it with his eyes closed !
Its just a simple birdsnest mod.
