Subject: [PATCH -next] HID: apple: Report Magic Keyboard 2021 battery over USB
Date: Sun, 2 Jan 2022 17:14:18 +0100 [thread overview]
Message-ID: <20220102161418.143775-1-jose.exposito89@gmail.com> (raw)
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.
