From 55633e681afb57c9a8ff8a3b22083d44cbaee9e8 Mon Sep 17 00:00:00 2001 From: YOSHIOKA Takuma Date: Sun, 22 Nov 2020 05:54:38 +0900 Subject: [PATCH] HID: elecom: add support for EX-G M-XGL20DLBK wireless mouse Enables three buttons (Fn1, Fn2, and Fn3) on the ELECOM M-XGL20DLBK wireless mouse. While this mouse is EX-G brand, report descriptor is a bit different from EX-G trackball mouse. To enable extra buttons, report should be rewritten in a similar way to trackballs, but with different position parameters.
