I’m running an ASUS P4P800 Deluxe motherboard in the system I built at home. I installed XP Pro a couple weeks ago after having run Win2K for awhile. XP wouldn’t recognize the USB ports as 2.0 and would only work with the sucky 1.0 slooooowwww format. I put off investigating until now, and it turns out it was an idiotically quick fix.
Open up Device Manager, scroll down to the USB controller — whoops! what’s that yellow question mark showing up?
Seems the USB controller wasn’t recognized during installation. A quick right-click to select “Update” fixed things — after I let XP search for drivers. The USB controller is now (correctly!) recognized as an Intel 8280 controller and I’m back up with the more better more better USB 2.0. Whew.
Should have put the nail in that coffin earlier!
