The receivers are mostly the same (and the air protocol obviously is compatible) but currently the Dinovo receivers are handled by hid-lg.c while the MX5x00 receivers are handled by logitech-dj.c. When using a Dinovo keyboard, with its builtin touchpad, through logitech-dj.c then the touchpad stops working because when asking the receiver for paired devices, we get only 1 paired device with a device_type of REPORT_TYPE_KEYBOARD. And since we don't see a paired mouse, we have nowhere to send mouse-events to, so we drop them. Extend the existing fix for the Dinovo Edge for this to also cover the Dinovo Mini keyboard and also add a mapping to logitech-hidpp for the Media key on the Dinovo Mini, so that that keeps working too.
