    By mistake I forgot to assign IRQ to usb in the bios option screen.
    What I don't understand is why all my USB devices still worked, even
    using my wireless keyboard with the sensor connected to a usb port I
    was able to access the bios and use the keyboard. I know XP assigns
    IRQ's independent of the bios setting anyway but my keyboard still
    worked before the OS was loaded. Is assigning an IRQ to usb not
    necessary or what?
