[Bug 1398035] Re: grub suddenly unable to get keystrokes from wireless keyboard and mouse

[Gordon Fitch]

The menu I saw offered different versions of the operating system, one
per line.  Since both the keyboard and the mouse were apparently not
effective, pressing 'C' would presumably have no effect.   The choices
were different after I installed 14.04 and tried that, but the failure
to receive anything from the mouse or keyboard was the same.

Title:
  grub suddenly unable to get keystrokes from wireless keyboard and
  mouse

Status in grub2 package in Ubuntu:
  New

Bug description:
  Problem appeared after automatic update of version 12.04,  (12.04.5)
  and also after trying to update to 14.04.  Keyboard, mouse work OK
  with previous versions and LiveCD of 12.04.1.  In 12.04, loader
  presented menu from which selection could not be made with either
  mouse or keyboard and did not time out.  In 14.04, could not select
  from menu but menu timed out.

  Substituting old-style keyboard and USB mouse caused problem to
  disappear (thus far).  Boot is normal, computer is now running
  normally.

  Ubuntu versions: see above.

  Wireless keyboard is Logitech Y-RAK73.  No legible information on
  mouse or receiver.

  Attempted to use Apport, but it crashed.
