This means you can basically hand over one (or more) of the usb plugs on your host to the guest and whatever device is plugged in there will show up in the guest. Usage: -device usb-host,hostbus=1,hostport=1 You can figure the port numbers by plugging in some usb device, then find it in "info usbhost" and pick bus and port specified there.
