Subject: [PATCH 1/5] HID: LG: Add support for Logitech Momo Force (Red) Wheel
Date: Tue, 19 Feb 2013 20:25:10 -0700 [thread overview]
Message-ID: <1361330714-5217-1-git-send-email-simon@mungewell.org> (raw)
This patch provides a modified report descriptor to split accelerator
and brake, and adds the 'NO_GET' flag to prevent it hanging on
connection.
Note: for convience this patch is against the follow patch which was applied
earlier this week.
