From b201fe49eeb8f72ec42071037e3dc3e7fc257efb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jos=C3=A9=20Exp=C3=B3sito?= Date: Mon, 28 Nov 2022 17:57:05 +0100 Subject: [PATCH] HID: multitouch: fix Asus ExpertBook P2 P2451FA trackpoint MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 4eab1c2fe06c98a4dff258dd64800b6986c101e9 ] The HID descriptor of this device contains two mouse collections, one for mouse emulation and the other for the trackpoint. Both collections get merged and, because the first one defines X and Y, the movemenent events reported by the trackpoint collection are ignored. Set the MT_CLS_WIN_8_FORCE_MULTI_INPUT class for this device to be able to receive its reports. This fix is similar to/based on commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for some devices").
