I'm thinking about getting the Kana. I know about feet replacement program and the need to update its firmware already. But I will use the mouse under Linux and a Windows PC where I can't install anything.

This means that I need confirmation that:
1. all of the buttons will be recognized by Linux and no-drivers Windows
2. firmware update is applied once and doesn't need drivers to upload it every reboot
3. the mouse will remember profile (like having lights disabled) when connected to a computer without drivers.

Is there a Kana Linux user? Or someone who could confirm this for me? Many thanks in advance!
