Did you hide the USB Device from Dom0? Sounds like a problem that I 
experienced when testing network cards.
The guest kernel tries to shutdown the USB device although it is still 
in use in dom0 and thus crashes the whole system. It's just a guess. So 
look for
kernel          /boot/xen-2.0.7.gz dom0_mem=262144 
physdev_dom0_hide=(00:04.0)
in your menu.lst and hide your own PCI address that is used by your USB 
Host controller if you did not already do so.
=>physdev_dom0_hide=("YourDeviceHere")

Andreas
