Return-Path: From: Antonio Ospite To: linux-bluetooth@vger.kernel.org Cc: Antonio Ospite , Bastien Nocera , Johan Hedberg Subject: [PATCH BlueZ v2 3/3] Add playstation-peripheral plugin: USB pairing and LEDs settings Date: Wed, 18 Apr 2012 11:38:11 +0200 Message-Id: <1334741891-11869-4-git-send-email-ospite@studenti.unina.it> In-Reply-To: <1334741891-11869-1-git-send-email-ospite@studenti.unina.it> References: <1334741891-11869-1-git-send-email-ospite@studenti.unina.it> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Add a plugin which handles the connection of a Playstation peripheral, when a new hidraw device is connected the plugin: - Filters udev events, and select the Playstation peripheral - Sets the Master bluetooth address in the peripheral (USB pairing) - Sets LEDs to match the joystick system number if needed (for USB and BT) - Adds the device to the database of the current default adapter (BT association) Signed-off-by: Bastien Nocera Signed-off-by: Antonio Ospite --- For the first review round plugins/playstation-peripheral.c is the most interesting file, in particular the handle_device_plug() and peripheral_pair() functions.
