Subject: [Patch-V2 1/6] INPUT: xpad: Add minimal support for Logitech G920 Wheel
Date: Thu, 12 Nov 2015 09:25:30 -0700	[thread overview]
Message-ID: <1447345535-2912-2-git-send-email-simon@mungewell.org> (raw)
In-Reply-To: <1447345535-2912-1-git-send-email-simon@mungewell.org>

When plugged in the Logitech G920 wheel starts with USBID 046d:c261
and behaviors as a vendor specific class. If a 'magic' byte sequence
is sent the wheel will detach and reconnect as a HID device with the
USBID 046d:c262.
