Strange one this, I used to have my USB ports at version 2.0 and for some strange reason they have reverted to version 1.1
When a USB device is initially connected, the device is reported as "not recognised" and fails to work.
I have Un-installed the USB ports and re installed (the drivers appear to be correct for USB version 2.0 operation)
Restore points are turned off due to virus issues.
XP at SP2 and all updates are current.
ACER laptop BIOS is up to date (Aspire 7000)
Any clues anybody.

No updated drivers found, but I will check for corrupt drivers

All devices previously worked as version 2.0

Its possible your USB drivers have become corrupted. You might want to check for updated versions in the Device Control Panel.

Hi, you may find the reason is that the device you are connecting is usinig more power than would be normally allocated to the usb port. Windows will recognise it as a usb device and reduce the power outage, this results in the device being seen as usb 1 instead of 2. You need to use a pwered hub or plug the device into the back usb ports and you won't have a problem.
Good luck

if it worked before, try a System Restore. That may help

try to look for Updates like Mr. Spock told you.
Or try to get it repaired or get an external usb adapter.
(I would get Windows Vista)
