You can't pass the port itself. You can pass individual devices attached to a port, but the latency can get weird sometimes. I had pretty significant problems when I did it that way. I opted to use Francisco's solution above, with a slight adjustment. I have a dedicated card that gets allocated to the VM. Connected to that, and to one of the host's USB ports, I have a USB A/B switch. Connected to the switch is a 4 port hub. Connected to the hub is my keyboard and mouse. All I have to do to switch the inputs from the host to the guest and back is to choose A or B on the switch, and a few seconds later all input is directed to the correct location.
