Well, you can't use the USB inside windows anyways, as you can't give
PCI devices to Windows, as Windows is a HVM domain and currently doesn't
supoort PCI passthrough - this has to do with the fact that you either
need dedicated "Virtual-aware" drivers or you need to have an IOMMU -
neither of which are in existance today [you'll also need some code
somewhere that lists the PCI devices to the Windows domain - probably
about two days worth of work, so trivial compared to comming up with the
IOMMU hardware or virtual-aware drivers].
