Title:
  cannot enter cryptsetup passphrase with wireless keyboard

Status in initramfs-tools package in Ubuntu:
  Expired

Bug description:
  After upgrade from 14.04 to 14.10 it became impossible to enter
  passphrase for LUKS root partition in graphical dialogue. Ctrl-Alt-
  Delete worked fro rebooting and on the second boot the text mode came
  up and the passphrase could be entered.

  Now after upgrade to 15.04 I no longer can reboot in the graphical
  mode with Ctrl-Alt-Delete with my wireless logitech keyboard. I
  managed to find old wired USB keyboard that behaves exactly the same
  as the the wireless was in 14.10. No input in graphical mode but
  rebooting is possible, text mode works fine.

  In fact, I was hoping that upgrade to 15.04 will solve the problem but
  it got worse.

  I have tried adding modules hid_generic, hid-logitech, hid-logitech-dj to module list for initrd as suggested by different bug reporst. No change there.
  I have tried changing BIOS settings but only disabling Legacy USB option made grub boot menu unresponsive.
  Both keyboards are working fine once the system is fully booted.

  I have noticed that when the boot goes to text mode the wired keyboard
  is unresponsive for a short period in the passphrase dialogue and
  comes to live after flashing its lights (probably some driver is
  loaded behind the scene?).
