Not sure if it interests you, but I wired up some pedals as from the BYO wheel/pedals site...
I found that even in XP, I was losing calibration, and the cursor in the Control Panel test screen was pretty jittery...
I tried a Gameport > USB converter that I had lying around, and it fixes it a treat! The cursor doesn't jitter around, and the calibration stays spot on. Oh and incidentally, I don't ever disconnect the pedals as they are a permanent fixture in my cab.
I also have 2 AKI's for other controls, and I must say they are a lot easier and work a treat also
