Pretty annoying if you want to specify something by USB "port path" - most common example being mapping an USB port into a VM (regardless of what's plugged into that port.) cf. qemu's "-device usb-host,hostbus=1,hostport=…" option … the obvious workaround is to map "both" ports into the VM …

  Having more than one copy of a device is quite common. Think USB to serial adapters or test equipment or license tokens.
