Thanks Alex for sharing & confirming!  I had no idea you could use USB
passthrough with SPICE.  I guess this method is better as it only
enables the "passthrough" while the SPICE session is going on (and not
permanently as long as the VM is powered-on in the regular mehtod).

Thanks, much appreciated!
