My PC's USB ports are not recognising my memory stick or camera card reader (which are working on the laptop). It does not matter which port I insert them into I still get 'device not recognised'. I tried to update/find a better driver for them through device manager and the wizaed but there was nothing available. The mouse, printer and keyboard are still working.

I am wondering whether the fact I recently plugged in an old Epson GT7000 scanner may have something to do with this. I recall ages ago I had to download a driver for it as the old CD had gone missing or was for 2000 (can't remember). This time I was prompted to find a driver for the Twain 32 or something like this which was duly found in the hard drive and there was a warning that things could go wrong on the install screen and maybe they have.

Does anyone have any suggestions? Is there a simple way to go back to default USB settings? Thanks.

Did you try memory stick, and camera card on another computer?

Go to Device Manager, and uninstall USB Controllers.
Restart computer, and they'll bee automatically reinstalled.

Yes they worked in other computer.

I uninstalled USB controllers as you suggested. They reinstalled OK but ports still not working.

Problem solved: Found a link which suggested shutting down and removing power lead and whaddya know it worked: something to do with residual power and USB ports playing up when they have not been used in a long time.
