I've just finished a driving cab which at the moment is set up to be able to play PC and PS2 games. The problem I have is that I cannot get my PS2 to recognise a steering wheel, I've tried 3 different ones now and none of them work on my machine although they work on my friends.
All other controllers work no problem on my machine, light guns, Eye Toy etc etc except steering wheels.

All of the wheels I have tried are force feedback and my PS2 is about as old as you can get as I got it when they were first released in late 2000 (?).
Has anyone heard of this problem before or know of some sort of compatibility issue with the early PS2's? I'm baffled and can't find anything on the web about it.
I'm dying to play GT3 in my cab so I'm looking at buying one of the new PS2's so as to be able to.
Thanks
