I have a PS2 Wheel (looks kind of like
this, but with out the foot pedals) that I'd be willing to give you. The cord isn't a USB plug though. It has the same hub, plug, end, whatever you want to call it, as a PS2 controller. But, i found
this PS2 controller adapter for $7.99 online thats meant to switch it over to a PS3, but thats just a USB so it should convert fine.
PM me if you want to know more.
