From: Ondrej Zary Date: Thu, 27 May 2010 06:30:54 +0000 (-0700) Subject: Input: usbtouchscreen - support bigger iNexio touchscreens X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=388bbcade41ee68d2d1ebb51a538380ea48ae599;p=linux-beck.git Input: usbtouchscreen - support bigger iNexio touchscreens Bigger Nexio touchscreens not only send more data but also the header values are modified somewhat. Fix the header (it's a guesswork but it works at least on one 46" touchscreen with 2.00SMS firmware) and also increase rept_size.
