Subject: [PATCH v3] HID: logitech-dj: Add support for a new lightspeed receiver iteration
Date: Sat, 04 May 2024 14:40:10 +0000 [thread overview]
Message-ID: <20240504143847.747890-1-mavchatz@protonmail.com> (raw)
The lightspeed receiver for the Pro X Superlight uses 13 byte mouse reports
without a report id. The workaround for such cases has been adjusted to
handle these larger packets.
The device now reports the status of its battery in wireless mode and
libratbag now recognizes the device and it can be configured with Piper.
This receiver has new descriptors, which have been added. The mouse
descriptor has 5 extra vendor defined bytes at the end, while the keyboard
one has a different report layout and minimums/maximums. As such, mice
with key press macros and keyboards that use this receiver misbehave
without them.
Fixes: 9d1bd9346241 (HID: logitech-dj: Add support for a new lightspeed receiver iteration)
