Guillemot race leader force feadback

Hi, i have this racing wheel for my computer. I bought it a couple years ago when win98 was still around and it worked great. But I wanna use it in winXP and for some reason i can't. Windows does not detect it(it's connected by a serial port not USB ) Anyways, i have tried all possible drivers for the thing and I just cant get it to work. BTW, i'm using an Asus k8v se deluxe.
Thanks
