From 0aa45fcc42d82753a257abbc7138922d8250e06f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jos=C3=A9=20Exp=C3=B3sito?= Date: Sun, 12 Dec 2021 19:20:59 +0100 Subject: [PATCH] HID: magicmouse: set device name when it has been personalized MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If the Apple Magic Trackpad 2 has been connected to a Mac, the name is automatically personalized showing its owner name. For example: "José Expósito's Trackpad". When connected through Bluetooth, the personalized name is reported, however, when connected through USB the generic name is reported. Set the device name correctly to ensure the same driver settings are loaded, whether connected via Bluetooth or USB.
