is it the older Xbox 360 Wireless Racing Wheel? There are no such thing as drivers for the console, so you don't need to worry about that...
If you're using it on the pc and it's weak according to wiki that wheel doesn't have ffb support on the pc either. http://en.wikipedia.org/wiki/Xbox_36...s_Racing_Wheel
Another thing that is noteworthy is that it needs to be plugged in for FFB to work.
I do know that on the logitech wheels like the Driving Force Pro there was a button combination to adjust the amount of FFB it produced. Hope any of that helps.
