Plug in any USB2 device and XP pops up message claining port is USB1.1

[zero]

If I connect ANY USB Highspeed (USB2) device to ANY usb port, and even if it is the only USB device, I always get the
pop-up message... XP Pro SP2 is always giving me that same message "this device can perform faster if you connect it to
a high-speed usb 2.0 port".

The Bios shows USB Highspeed is enabled. The XP Device Manager shows "USB Enhanced" controller. MB is ASUS P4S8X-MX
which is USB2 and BIOS is properly configured for USB Highspeed.

I can't make any sense of this. Indeed I have verified that the data transfer speed is snail slow.

Maybe something at one of these help sites.

Rather than multi post, you should cross post your question. That way any
reply that you get will show up in all the newsgroups that you pose your
question.
