    Cool, input devices have been one of the weakest parts of the Linux kernel. It does seem to be speeding up a little bit but is still months after release. I'm thinking of picking up a G305 or G Pro Wireless and it doesn't look like either of them are fully supported (and the DPI toggles and performance/battery mode toggles are in software so having support would be very helpful).

      Sorry for asking, but what's the difference compared to without the driver? I've been using my g900 for like year now in wireless mode.

            device name probably with lsusb, list of modules with lsmod. also you could check dmesg or journalctl -f during receiver insertion.

              lsusb

              Also, when I think way back, my G700 mouse I also had was working perfectly fine in wireless. I'm just curious what the difference is...

                Without tools as such, your mouse is simple standard USB mouse the exports all the standard features that any other USB HID device can export :
                Buttons, Axis. (with the wheels of the mouse showing up as additional axis and/or button)
                That's it.
                But that's also enough for 99% of use cases.

                With tools as such, you can access all the additional bell and whistles which aren't standardized yet in USB HID protocol.
                (Switch on coloured LED lights, switch the mouse sensitivity between different DPI settings, map hardware macros to buttons, change the wireless binding to devices, etc.)

                  Ah, I see, thanks for clarifying.

                    as you can see, your mouse is called 'logitech inc' or 'logitech receiver'. i guess it will be called better and maybe even handled by non-generic module
