You need to get the device URI for the printer and then see if any
of the local printers has that URI.  Probably you can run the USB
backend to get the current list of devices and then check them all
against the printer list...

FWIW, we'll have hotplug support in CUPS 1.2 via the new cups-deviced
stuff...
