USB in NT does exist in one form that I know of. Since NT doesn't have USB support at the kernal level you'll be out of luck with any USB devices like cameras and mice. The one exception is with USB keyboards. If your machine has USB keyboard support at the bios level, NT will recognize it just fine. There is one caveat and that is that the numlock/capslock/scrollock lights won't work, but that's no big deal. 🙂
