Subject: [PATCH v2 20/20] HID: hid-multitouch: Fix contact count on 3M panels
Date: Wed, 5 Sep 2012 17:09:37 +0200 [thread overview]
Message-ID: <20120905150937.GA260@polaris.bitmath.org> (raw)
In-Reply-To: <CAN+gG=FwXaSWN_AYnU7Vpxn4GcWYG3Bf100P0QD_8cQfEnGc7A@mail.gmail.com>
Some devices report the number of contacts via the unreliable
CONTACTCOUNT usage, rather than using the CONTACTMAX feature.
Without this patch, the 3M devices are constrained to the default
maximum of ten fingers.

Benjamin, are you ok with 0x506 being treated this way as well?
Thanks,
Henrik
