From 5b01b3b8b122fde7fbe116803f7863667b4c5beb Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Fri, 3 Nov 2017 18:29:47 +0100 Subject: [PATCH] HID: Wacom: switch Dell canvas into highres mode The Dell Canvas exports 2 collections for the Pen part. The only difference between the 2 is that the default one has half the resolution of the second one. The Windows driver switches the tablet into the second mode, so we should behave the same.
