Date: Fri, 12 Nov 2021 14:55:11 +0100 Message-Id: <20211112135511.29573-1-linux@zary.sk> X-Mailer: git-send-email 2.20.1 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-input@vger.kernel.org Iiyama ProLite T1931SAW does not work with Linux - input devices are created but cursor does not move. It has the infamous 0eef:0001 ID which has been reused for various devices before. It seems to require export_all_inputs = true. Add it to mt_devices[] as MT_CLS_WIN_8 to fix the problem. Hopefully there are no HID devices using this ID that will break. It should not break non-HID devices (handled by usbtouchscreen).
