I've did a boot/login with

Linux quadrige 3.12.0-031200rc7-generic #201310271935 SMP Sun Oct 27
23:46:05 UTC 2013 i686 i686 i686 GNU/Linux

and had the same behavior. (I've added syslog2 from that kernel)

Maybe I need to point out again, that in any case the camera is working
fine. This bug is all about the disturbing long delay for the
initialization of the camera that blocks any login with lightdm.

Title:
  Microsoft® LifeCam HD-6000 takes long time to initialize

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a Microsoft® LifeCam HD-6000 connected to my computer.
  Before I can login using lightdm I have to wait about 15 seconds, when the camera is plugged in. The initialization of the camera seems to block the input. After I logged in there is another delay of about 15 seconds when the initialization of the camera seems to happen again. A workaround is to just unplug the camera and plug it back in when it's needed, but as it worked fine with 13.04 I would be happy to not do the unplug/plugin dance.

  I added part of the syslog where this initialization seems to happen.
