  Logitec (Keyboard)
  Mint (older version)
  Works fine with some minor problems
What works:

Out of the box normal keyboard funtions work, inc volume and media keys
Built in sound card works with no issues

What doesn't work:

G-keys, backlight switching and macros don't work at all, G-keys only work as function keys.

What was done to make it work:

Followed these instructions http://www.russo79.com/gnome15/download/mint

Worked almost perfectly, ONLY USE THE DIRECT DRIVERS, NOT THE KERNAL ONES, otherwise you will need to press buttons more than once to get them to work.

Additional notes:

As of Linux Mint 17.2 (July 2015)

You cannot get the gnome15 drivers anymore as it seems the original devs stopped support for it, so no more g-key or backlight support
