    My XP box doesn't have any USB hub attached. It does have
    as many as 4 USB devices attached. Device Manger lists five
    USB Root Hub. Why does it do that?

    The root hub isn't a "hub" in the external sense. Every USB controller has
    to have a hub associated with it. It is how Windows (or any OS)
    communicates with the physical USB device.
