From 1b723e8dc81b23141bfb8991e002073b17fd0199 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Wed, 23 Nov 2011 10:54:34 +0100 Subject: HID: multitouch: correct eGalax a001 protocol This device use another protocol while sending the events. It's the same as the one described as "serial" by Microsoft. We are keeping here the sn_move and sn_pressure parameters for egalax devices.
