With a USB Hub

    Start with the XBox controller OFF.
    Turn on the console using the front panel.  Leave the controller off.
    Plug the CronusMax into the console.
    Plug the hub into the CronusMax input port with the XBox controller connected to one port and the Quadstick connected to the other.
    The CronusMax display should display a number after a few seconds.
    If U/A continues to flash, reverse the order of the ports used by the Quadstick and the XBox controller.
