Title:
  USB attached keyboard and mouse don't work at the login time to Ubuntu
  Trusty Tahr 64 bit

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After the update to kernel 3.13.0-51-generic from kernel 3.13.0-45
  generic, in Trusty Tahr 64 bit, USB devices don't work at login time.
  The login screen comes up but one cannot login because both the
  keyboard and the mouse are USB attached devices, and are not working.

  I was able to login and use the computer by using the advanced mode in Grub and then reverting to kernel 3.13.0-45 generic.
  I could also login if I used the advanced mode and then loged in to the recovery mode of kernel 3.13.0-51 and just selected the resume entry in the offered menu.
