    • Systems and methods are provided that enable identification of an accessory device or other peripheral device via a serial communication link. An electronic device (e.g., a media player or portable media device) may identify an accessory device using a serial communication link when the accessory device is attached or coupled to the electronic device. Based on serial communications, for example, the electronic device may discover and identify an accessory device to determine whether one or more preferences or functionalities should be set or enabled. The electronic device may also discover whether an accessory device or its manufacturer, distributor, or retailer is authorized or licensed to enable certain functionalities or set certain preferences when connect to the electronic device. Therefore, aspects of a serial communication link that may already exist in many electronic devices for data communication usage may be repurposed to provide identification or authorization of accessories or other peripheral devices.
    • 提供了能够通过串行通信链路识别附件设备或其他外围设备的系统和方法。 当附件设备附接或耦合到电子设备时,电子设备(例如,媒体播放器或便携式媒体设备)可以使用串行通信链路识别附件设备。 基于串行通信,例如,电子设备可以发现并识别附件设备,以确定是否应该设置或启用一个或多个偏好或功能。 电子设备还可以发现附件设备或其制造商,分销商或零售商是否被授权或许可以启用某些功能,或者在连接到电子设备时设置某些偏好。 因此,用于数据通信使用的许多电子设备中可能已经存在的串行通信链路的方面可能被重新利用以提供附件或其他外围设备的标识或授权。
