From 8ae5c16c9d421d43f32f66d2308031f1bd3f9336 Mon Sep 17 00:00:00 2001 From: José Expósito Date: Tue, 8 Feb 2022 19:50:09 +0100 Subject: HID: apple: Report Magic Keyboard 2021 battery over USB MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Like the Apple Magic Keyboard 2015, when connected over USB, the 2021 version registers 2 different interfaces. One of them is used to report the battery level. However, unlike when connected over Bluetooth, the battery level is not reported automatically and it is required to fetch it manually. Add the APPLE_RDESC_BATTERY quirk to fix the battery report descriptor and manually fetch the battery level. Tested with the ANSI, ISO and JIS variants of the keyboard.
