* HID protocol status
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. Signed-off-by: Hans de Goede <hdegoede@redhat.com> --- Changes in v2: -Remove chunk to pick a better name for hidpp devices, this is replaced with a more generic fix in a separate patch -Add support for mouse on index 2, numeric-keypad on index 4 -Use a new group for 27MHz, so that logitech-hidpp.c can check for this to enable 27MHz specific behavior, rather then have it guess based on the descriptors. This also allows removing some 27MHz descriptor hacks from logitech-dj.c, so it simplifies things on both ends --- drivers/hid/hid-lg.c | 2 - drivers/hid/hid-logitech-dj.c | 94 ++++++++++++++++++++++++++++++++++- drivers/hid/hid-quirks.c | 1 - include/linux/hid.h | 1 + 4 files changed, 94 insertions(+), 4 deletions(-)
