Title:
  loading firmware into hplj1000 twice

Status in foo2zjs package in Ubuntu:
  New

Bug description:
  /lib/udev/hplj1000 doesn't handle another $DEVNAME case when udev
  calls it twice.

  Udev calls the script twice for some reason on the system described
  below.

  At first, udev calls hplj1000 with "/dev/bus/usb/004/059" as a $DEVNAME which is not desired/not supported.
  Then it calls the script once again with "/dev/usb/lp0" as a $DEVNAME which is desired and must be used to load a firmware to.

  The problem is that the script handles only "/dev/usb/usb*" case but not the "/dev/bus/usb/*".
  This leads to firmware being loaded twice which causes HP LaserJet 1000 to hang and stop processing tasks.

  Attached patch adds another case to the /lib/udev/hplj1000 script that
  silently exits if the script is called with undesired value.
