[Bug 1450989] Re: USB attached keyboard and mouse don't work at the login time to Ubuntu Trusty Tahr 64 bit


A workaround for this bug is:
Start the machine from scratch with all the USB devices plugged in.
Wait for the Grub menu to show on the screen.
Using the keyboard select Ubuntu as the operating system to load.
Right after selecting the Ubuntu OS, disconnect the USB mouse (be it direct USB plug-in or remote).
When the Ubuntu login screen comes up it will be possible to use the keyboard to enter the user-name and the password.
Once the Ubuntu environment is established, reconnect the USB mouse., and use it normally.
Problem solved, although a bit annoying.
Hope this helps.

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

Status in linux package in Ubuntu:

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.
