Hi
Thnaks for the reply.
I have tried that and it still does not work.

After the reinstall I plug in the devices and it says found new hardware and
tries to find the drivers. I have never had to use a driver for a usb memory
stick. It tries to find some drivers and then comes back and says no drivers
are found. This is really weird. I have been using the devices without any
problems, very strange.

Any other ideas
