I'm not sure on the rules regarding virtual machines with WoW, you may want to read up on that before trying this out. With that said I have never tried to plug a USB switch (or sync) into a host PC twice so that your Hypervisor can provide distinct connections to the VM.

The only way I see this working out (and I'm no expert here) is if your host machine had a PCI add in card that provides additional USB ports. In terms of allocating physical hardware to one VM and not another, you might be able to plug 1 USB cable from the KM sync into the onboard USB and a second USB cable from the KM sync to the PCI USB card. In the configuration for the VM you'd make sure that one VM can only use the add in card and the other VM can only use the onboard USB. I have no idea if this would work or not and if WoW's ToS does not look kindly on playing in a virtual machine we may not want to even try.
