As posted today in our forums, Logitech is beginning to list "Linux compatible" products on their web-site. Sadly though at the moment, the list is still short with just showing off their M185 Wireless Mouse. A Linux compatible selector is shown next to Windows and OS X when browsing their products, which is a nice start but more is expected from the company.
Logitech hasn't officially released any Linux software or drivers for their gaming peripherals like advanced mice, keyboards/keypads, and audio products, but there is a growing independent software community.
It was also last month I noted a coming Linux gaming peripheral play. Besides Logitech, another company worth following for Linux-compatible gaming peripheral hardware is Roccat, although the brand is less popular in North America.
