The protocol is either USB HID class, or none at all.
In the former case You will have to implement an USB protocol device.

This could be done even without a specialized USB controller, a firmware-only driver and an AVR microcontroller are enough:

I saw a few AVR based joystick/steering wheel projects on the net, just google a bit, You should find something that will fit Your needs.
The latter case is simply a potentiometer connected do PC's game port.
