OK, now I understand. Looking at the registry parameters in W2K the
"Logitech Camera USB (Web)" device is listed with a Service value of

different than the ones that come with the Vision Command don't worry - I've
installed the new Logitech QuickCam 6 software which includes new drivers
and they do work with the Vision Command camera, however they are
significantly slower and I will probably remove them and reinstall the
original drivers (although the new v6 GUI for the camera alone is nicer).
