From ac2423c975dbd3e8c2afc6dec53ee25be38f723b Mon Sep 17 00:00:00 2001 From: Aaron Armstrong Skomra Date: Wed, 25 Jan 2017 12:08:40 -0800 Subject: [PATCH] HID: wacom: generic: add vendor defined touch Add vendor defined touch to support the second generation Intuos Pro. Previously all generic Wacom devices used true HID to report their touch.
