Okay, I think I've come up with a workaround for this problem. I'm  
still trying to get this to work, since there are some bugs, but the  
idea is to make use of the motherboard's IOMMU and use PCI passthrough  
to attach one of the USB controllers to the guest domain. Then that  
wretched USB device can flip its product ID all it wants and the  
system will continue to work.

Cheers,
