[Bug 722411] Re: 60-persistent-input.rules does not create a symlink for interface #0 (with multi-interface USB devices)

[a7x]

Closing as invalid.  The premise of this bug report is that the symlink
without the interface number is always associated with the last
interface, which isn't correct.  According to the udev man page, the
device that gets the interfaceless symlink is undefined because
link_priority isn't set.  I have filed bug #1057824 about assigning
link_priority values so that the interfaceless symlink consistently
points to the interface 0 device.

Title:
  60-persistent-input.rules does not create a symlink for interface #0
  (with multi-interface USB devices)

Status in “udev” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: udev

  Commit 32567f8 in the upstream udev git repository [1] was meant as an
  enhancement to commit 5e9eb15 [2], which was made to fix bug #626449.
  Unfortunately, commit 32567f8 (which is present in udev_166-0ubuntu1
  in natty) is wrong.

  The original symlink -- the one without the interface number -- points
  to the device file for the last interface, not interface #0.  With a
  two-interface USB device, both /dev/by-id/usb-<serial>-<class> and
  /dev/by-id/usb-<serial>-if01-<class> point to the same device file
  (the one for the second interface).  With commit 32567f8, no symlink
  for the first interface is created.

  Reverting commit 32567f8 from the upstream udev Git repository should
  fix the problem.
