.. will reveal which process is eventually having ulpt0 open, and
causing 'device busy'.
The usb backend seems to get this error while trying to open /dev/ulpt0.

Please also make sure that either the cups user or cups group has read
and write access to /dev/ulpt0.
I think most people use permissions like: root:cups 0660 (-rw-rw----).
