Public bug reported:
I updated an AMD64 box to karmic recently. There was always a HP Laserjet 5P
running on that machine (worked until the update).
It took me ages once to find out the correct device string (something like
hal:/org/freedesktop/HAL/usb_no_serial_if0_serial (out of my head ..)), because
the printer is connected via a usb2parallel adapter.
Following the Bugs regarding the move from hal to udev, I blacklisted
usblp (which detected the printer somehow and created /dev/usblp0) as
recommended. Afterwards neither lsusb nor lpinfo and all those tools
detected the printer or the parallel/usb adapter anymore.
Now I once for testing loaded the usblp module again ang get these in kern.log:

Any idea to how to get that printer running again without hal backend?
