G13 does not work with Linux out of the box. Not a single key works.
Normally, a Logitech gaming mouse with on-board memory such as Logitech G600 Gaming Mouse or Logitech G700s Mouse , you can setup in Microsoft Windows, then just plug in in Linux, your customized buttons will work. I was expecting the same for the G13. But no, it doesn't work.
But there's this linux driver you can try.
