I found using USB pass-through quote annoying to use on a daily basis. Having to re-attach when disconnected and vm's not starting when a USB device is missing, ugh.
If you still have a free pci-e slot in your system I recommend buying an add-in USB card for ~10 in whatever your currency is and use pci-e pass-through. Makes life so much easier. Eg I used the pci-e x1 slot under my gpu for this with a low-profile pci-e riser.
