I had the same problem with a K800 Keyboard from Logitech.
a better way would be to edit the file
/etc/initramfs-tools/modules

I can confirm that this bug exists, using a Logitech K330 wireless
keyboard and a Logitech M215 wireless mouse (part of the same wireless
keyboard/mouse package of course). Under 14.04.2LTS and 14.10, there's
