Subject: [PATCH] HID: sony: Add support for Guitar Hero Guitars
Date: Wed, 30 Oct 2019 22:29:56 +1300	[thread overview]
Message-ID: <20191030092956.17934-1-sanjay.govind9@gmail.com> (raw)

From: Sanjay Govind <sanjay.govind9@gmail.com>

Guitar Hero Guitars use the accelerometer x axis for tilt. Currently,
they are treated as a regular HID device, and this does not allow the
usage of the accelerometer. Add in support for both the PS3 and the 
PC guitars (they are the same guitars, with different vids and pids).
