[Qemu-devel] info usb lists non unique device entries?

Using Arch qemu 2.1.0-2

I haven't actually made use of usb_del but I expect that I would 
normally run something like `usb_del 0.4`  (after usb eject in quest).

initial usb line is -usb -usbdevice host:046d:c313 -usbdevice

added via qemu monitor usb_add host:0480:a004 after boot which works 
fine during usage
