Subject: [PATCH 2/3] Input: add support for DragonRise PID 0011 gamepad
Date: Thu, 13 Jan 2011 21:56:42 +0300 [thread overview]
Message-ID: <1294945003-7687-3-git-send-email-spbnick@gmail.com> (raw)
In-Reply-To: <1294945003-7687-1-git-send-email-spbnick@gmail.com>
Add support for DragonRise Inc. gamepad with USB PID 0x0011 by fixing its report
descriptor. This mainly removes spurious axis.
