    Abstract: 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.

    Abstract translation: 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。

    Abstract: A portable computing device (PCD) can selectively supply power to an accessory during PCD hibernation. In some embodiments, the PCD's default behavior is to disable accessory power output during hibernation, and this default behavior can be overridden in response to a request from a connected accessory. The accessory can use the power supplied during PCD hibernation to detect user input (or other) events and wake the PCD from hibernation in response to a detected event. Some accessories can wake the PCD by emulating accessory detachment and reattachment.

    Abstract translation: 在PCD休眠期间，便携式计算设备（PCD）可以选择性地向附件提供电力。 在一些实施例中，PCD的默认行为是在休眠期间禁用附件功率输出，并且响应于所连接的附件的请求，可以覆盖该默认行为。 附件可以使用PCD休眠期间提供的电源来检测用户输入（或其他）事件，并响应于检测到的事件将PCD从休眠状态唤醒。 一些配件可以通过模拟附件拆卸和重新连接来唤醒PCD。
