From c9121cf637331b6fc07a60708c6ca0a161e7deb5 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 20 Apr 2019 13:21:56 +0200 Subject: HID: logitech-dj: add support for 27 MHz receivers Most Logitech wireless keyboard and mice using the 27 MHz are hidpp10 devices, add support to logitech-dj for their receivers. Doing so leads to 2 improvements: 1) All these devices share the same USB product-id for their receiver, making it impossible to properly map some special keys / buttons which differ from device to device. Adding support to logitech-dj to see these as hidpp10 devices allows us to get the actual device-id from the keyboard / mouse. 2) It enables battery-monitoring of these devices This patch uses a new HID group for 27Mhz devices, since the logitech-hidpp code needs to be able to differentiate them from other devices instantiated by the logitech-dj code.
