The information in the driver is embedded into the Wii games that support this wheel. The game has to be inspected to check what commands are being sent via USB to the wheel and to resend those commands via Windows.
Dolphin does have USB HID support in the latest version (4.0 or newer). You could try downloading zadig and installing the WinUSB driver into the wheel, then start up the game and hopefully the wheel will start working.

This wheel is rare. I am interested in adding emulation of it in Dolphin. Keep in touch.
