The receiver of the G900 is similar to a Unifying one. However, if we switch the receiver into the DJ mode through hid-logitech-dj, the reports emitted by the mouse are from a new kind. Instead of finding out what they are, and given that only one device should be connected to the receiver, just use hid-logitech-hidpp. The battery is not yet supported in the kernel, but at least the input nodes are now named after the mouse.
