Thank you for your reply. I found a Microsoft article explaining a workaround.
I unplugged the camera and, after boot up, plugged it into an other usb root hub.
The cam then was being by found and worked. Today again not. I think its an
issue with messenger software I have installed. However the cam now is up an
running. I downloaded an update that I installed, and downloaded and installed
the latest version of the messenger program afterwards.
I hope its gonna working tomorrow after reboot. The cam but was a nice piece
of hardware. It got a round base socket on that it's sitting on my CRT, that can
be flipped open in part to also clip on top of a LCD. Very nicely done. I do
love such details. The other cam I've had before could not even just sit on top
of rhe screen since it's cable was pulling the lens upright.
I had the cam installed prior than now, and I recall it was working fine back
then. Perhaps some issue with the messenger program that was new?
