I just purchased and installed a USB 2.0 PCI expansion card for my PC. XP auto-detected and installed the drivers for it just fine, but it gave me an error trying to install drivers for a "Enhanced Host Controller". Everything else is fine - I can plug USB devices into it, but if I try to plug in a USB 2.0-enabled device, like my iomega Zip 750 drive, I get an error saying that I'm trying to plug a high-speed device into a non-high-speed card. I've tried reinstalling the drivers - any other suggestions?

I may be wrong on this one, but I think you must have Service Pack 1 (SP1) for XP installed in order to use USB 2.0 hardware at the faster speeds. Otherwise it will continue to operate at 1.0 or 1.1 speeds.
