From b1ca42d2c2ff32fcd380e6667437139e6fb5f465 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Felix=20H=C3=A4dicke?= Date: Thu, 19 Nov 2020 09:22:32 +0100 Subject: [PATCH 1/6] HID: quirks: Add Apple Magic Trackpad 2 to hid_have_special_driver list MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Apple Magic Trackpad 2 is handled by the magicmouse driver. And there were severe stability issues when both drivers (hid-generic and hid-magicmouse) were loaded for this device.
