The proposed package fixes the more important issue of print queues not
auto-created at all for all non-IPP-over-USB printers, which is an
essential feature of Ubuntu (Plug'n'Print) which got completely lost.
The 3-minute delay on IPP-over-USB printers (which are still a minority
under the USB printers) is caused by the switchover from Upstart to
systemd is not covered. As the former issue is much more important the
SRU is worth it already without the fix for the latter issue. Therefore
I mark this "verification-done" to make the fix for the first issue
going into -updates and will issue another SRU as soon as there is a fix
for the other problem.

Title:
  IPP-over-USB support broken

Status in system-config-printer package in Ubuntu:
  Fix Released
Status in system-config-printer source package in Vivid:
  Fix Committed

Bug description:
  The support for IPP-over-USB printers in udev-configure-printer is
  broken, leading to the following two problems:

  1. If the printer connected to USB supports IPP-over-USB, the
  automatic generation of a print queue can hang for three minutes

  2. If the printer connected to USB does not support IPP-over-USB udev-
  configure-printer calls ippusbxd anyway and errors out, not creating a
  print queue.

  This occurs in Vivid and Wily.

  [Impact]

  All Vivid users with a USB printer will not get automatic setup of
  print queues (printer does not do IPP-over-USB) or a print queue setup
  delayed by around 3 minutes (IPP-over-USB printers).

  [Test Case]

  Connect a USB printer for which there is not yet set up a local print
  queue. Usually within some seconds a print queue is set up
  automatically for it. No queue gets set up, for IPP-over-USB printers
  it takes around three minutes to get a print queue.

  The proposed package fixes this problem.

  [Regression Potential]

  Very low. The patch is trivial and it affects only the automatic setup
  of USB printers. Network printer setup and manual setup of USB
  printers or printing on already existing queues is not affected.
