If I imagine it correctly (I don't have such a somewhat strange USB
printer to reproduce it): As long as a USB printer is not recognized
"as usual" by CUPS, you cannot set up a print queue for it "as usual".

One possible workaround in this particular case is to set up
the print queue manually via "lpadmin" as described at
"How to set up a print queue in full compliance with CUPS" in
http://en.opensuse.org/SDB:CUPS_in_a_Nutshell
using the DeviceURI "usb://Xerox/Phaser%206010N"
which was reported by the CUPS "usb" backend.

Another possible workaround when the CUPS "usb" backend does not detect
a DeviceURI for a USB printer which is actually accessible via /dev/usb/lp0
is to use a selfmade "careless backend for a single USB printer", see
http://en.opensuse.org/SDB:Using_Your_Own_Backends_to_Print_with_CUPS

If a printer is not accessible at all, it is useless
to try to set up a print queue for it, see
http://en.opensuse.org/SDB:Installing_a_Printer
