I have just built a win xp machine 3 ghz 512mb asus mobo, I have installed win xp sp1, sp2. When ever I plug a usb device in I get an error that says “for better preformance you should install that device into a usb 2.0 port. I checked the device manager and it says that I have enhanced usb installed, so I can’t figure out why I still get this error.
