I bought a Belkin USB 2.0 5 Port PCI card for my computer that runs XP SP2. The card seems to work fine except when I plug a Digital Camera conection into it, the colour on the monitor darkens and goes slightly blue green. It's recovers as soon as I take the connection out. The card has a webcam permamently connected and that works OK and doesn't change the monitor colour. Any ideas what could be causing this?
