Subject: [PATCH] HID: logitech-dj: Add support for G915 TKL receiver 0xc545
Date: Fri, 03 Jul 2026 17:28:06 -0700 [thread overview]
Message-ID: <eb945a79-d9ef-4194-be41-2ec81d6d8f3c@app.fastmail.com> (raw)
The Logitech G915 TKL has a lightspeed receiver with a product id of
0xc545. This receiver seems to behave like 0xc547 receiver.
Add a definition for this new receiver id and a mapping for the
recvr_type_gaming_hidpp_ls_1_3 type, the receiver now reports battery
status of the connected keyboard.
