I have a creative cam sitting on top of my pc and when first connected to a
usb 1 connector on the back of my pc gave horrible pictures like a low light
high contrast look. After adding a usb2 card and connecting it to the camera
it gives a sweet picture, and my printer is faster to boot!
Hope this helps,
