From da10bc252476a8d1d1bdf7b94502ad2cbd7f30b1 Mon Sep 17 00:00:00 2001 From: Mathieu Magnaudet Date: Sat, 22 Nov 2014 12:02:07 +0100 Subject: HID: multitouch: Add quirk for VTL touch panels VTL panels do not switch to the multitouch mode until the input mode feature is read by the host. This should normally be done by usbhid, but it looks like an other bug prevents usbhid to properly retrieve the feature state. As a workaround, we force the reading of the feature in mt_set_input_mode for such devices.
