Answer 2

as an option ... a separate physical server as a host for usb and usb over ip solutions, or hardware solutions of a similar plan

Answer 3

USB over IP is a free solution from usbip.sourceforge.net/
By the way, this is better than forwarding USB to a virtual machine - the virtual machine will not be tied to the hardware and, for example, it can be migrated.
