I plugged in a usb webcam, which a logitech communicate stx, into one of the ports on my computer, and then launched a viewer called cheese to see if it worked, which it did after about a minute of cheese searching for it. Then I plugged it into a different port so that the cord wasn't in front, and now cheese can no longer view it. It just gives out static and color bars, even if I try putting it back in the original usb socket.
