[PATCH] HID: logitech-dj: Add support for G Pro X Superlight 2 receiver

Posted by Nathan Rossi 3 months ago

The Logitech G Pro X Superlight 2 has a lightspeed receiver with a
product id of 0xc54d, this receiver behaves like the receiver used in
the original Logitech G Pro X Superlight (id 0xc547) including the 13
byte mouse reports.

This change adds a definition for this receiver id, and a mapping for
the recvr_type_gaming_hidpp_ls_1_3 type. With this change in place the
receiver now reports the battery status of the connected mouse over
wireless as well as exposing the HID interface needed for userspace to
perform additional configuration with libratbag/Piper.
