Too bad...what processor do you have?  If the processor itself supports it, 
then perhaps they'll release a BIOS update that supports it.  If not, then 
maybe getting a new processor for the box would do the trick??

At this time, I don't believe that functionality works.  It would be nice if it 
were the same as disks, network interfaces, etc., where you specified something 
like:

usb=['dev1', 'dev2', 'dev3']

but I think the multiple USB support for HVM domUs has only recently been 
added, so I'm sure the configuration will eventually support this.  Just not 
right now.
