Running WinXP Home SP3
I have three flash drives that have been working perfectly on both my
Desktop and laptop( WinXP ProXP3 ).
Suddenly they cause a "USB Device not recognised " message when
inserted into the Desktop. The laptop reads them perfectly.
The Flash drives are two different makes.
An optical mouse was picked up and installed immediately.
Device Manager shows no problem until Flash Drive is inserted when a
"unknown device" item appears.
I have tried without success to update the drivers for the USB
controllers but believe them to be OK as the Optical drive is picked up.
Your comments please,Richard
