Ok, I have a steering wheel (the Logitech Wingman Formula GP) but I can't find the software for it.
It's not on Logitech site etc.
cause now I use 1 pedal as clutch, but because I can't find a wheel software thing, I have done it as joystick with 2 axes and 4 buttons.
And now it thinks that clutch is a combined pedal, so if I press nothing in the clutch pedal, it has half clutch in game...

You can download the Logitech Gaming Software for your wheel here

The software is the same also for the Formula Force GP wheel too.
