Hi,
that's better done with the usb features, some very basic info here:
http://www.linux-kvm.org/page/USB_Host_Device_Assigned_to_Guest
you can google up more.
if you'll want to assign whole usb controller, that's possible too with
pci passthrough (requires VT-d), but seems you want only device passthrough.
