I see an error message if I use the USB webcam and the USB TV tuner card
at the same time. Although it only flashes for a half of a second when I
plug the last one in and then both are operating just fine. I don't use
them on a hub, but rather my laptop has 4 built in USB ports. I would
never purchase a laptop without at least 4 USB ports on it. :)
