I forgot to mention in my earlier post, that inside Device Manager you
should click "view devices by connection" radio button. That may provide
further clues.

We recently purchased a used Dell computer. When we first started it, not
all the drivers were installed. I installed all the drivers but one and
every
time we start the computer, Windows detects an unknown hardware device.
We
cannot find what this device is. Any suggestions?
