    This really sounds like something is still mounted and you are effectively
    ripping out the rug from under Linux's feet.

    Before you unplug the USB device you should 'rmmod <driver>' for whatver
    module it uses (look in 'lsmod' for a good guess).

    Then unplug the device and see what happens. If it starts to behave, I think
    you will find it will, then you can work out a more automagic approach.

    Cheers
