Subject: [PATCH 2/2] HID: elecom: add support for EX-G M-XGL20DLBK wireless mouse
Date: Sun, 22 Nov 2020 05:54:38 +0900 [thread overview]
Message-ID: <20201121205438.4092-2-lo48576@hard-wi.red> (raw)
In-Reply-To: <20201121205438.4092-1-lo48576@hard-wi.red>
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.
Signed-off-by: YOSHIOKA Takuma <lo48576@hard-wi.red>
