From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel van Vugt Subject: [PATCH v1 1/1] hid-magicmouse: Magic Trackpad has 1 button, not 2 Date: Thu, 13 Oct 2011 18:05:12 +0800 Message-ID: <4E96B7D8.3030005@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Return-path: Received: from mail-vx0-f174.google.com ([209.85.220.174]:45580 "EHLO mail-vx0-f174.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752274Ab1JMKFS (ORCPT ); Thu, 13 Oct 2011 06:05:18 -0400 Received: by vcbgb30 with SMTP id gb30so1343312vcb.19 for ; Thu, 13 Oct 2011 03:05:18 -0700 (PDT) Sender: linux-input-owner@vger.kernel.org List-Id: linux-input@vger.kernel.org To: linux-input@vger.kernel.org hid-magicmouse was advertising the Apple Magic Trackpad as having 2 buttons (left and right) when it actually only has 1 button. Advertising multiple buttons in turn makes the xorg synaptics code disable all button 2 and 3 emulation (using multi-finger clicks). So xorg users don't get working right/middle-click emulation out of the box. This patch makes hid-magicmouse correctly only report one real button for Magic Trackpad, which in turn makes xorg enable multi-finger click support to emulate right/middle buttons.
