Not sure about his specific problem, but there are issues with XP and the
TSW wheels. The recommended pots for use with XP are the 250K ones. I had
bought the 50K ones (88.00 for 4) trying to solve the problem before the TSW
site starting recommending the 250K ones which are only 12.00 each. It did
make my wheel better going to the 250K pots, but I still am not quite
satisfied with the stability. I have ordered the USB adapter from TSW also.
Phillip Malphrus Jr. has recently changed his pots to the 250K ones and
added the USB adapter, and his wheel now works great, even in F1-2001 which
everyone was having issues with when using split axis on the TSW.
