XP Driver works on some PCs, not others

I have a problem the with usb driver that works fine on 2
computers, but fails on 2 others. The driver is for a
USB device that allows connecting a Playstation
controller to the USB port of a computer. The driver
installs fine, but fails to start (code 10) when the
deivce is plugged in.

I have tried this on 4 different computers. It works
fine on 2 and fails on the other 2. The computers all
have XP/SP1 with the same updates from Windows Update. So
far the only difference I can see is that the computers
with an ATI video work OK, while those with nVidia cards
do not.

Does anyone know how I can determine what is different to
make the driver work on some computers and not others?

Thanks
