    摘要： Accessory device authentication techniques are described. In one or more embodiments, connection of an accessory device to a host computing device is detected. Responsive to the detection, an authentication sequence may occur to verify an identity and/or capabilities of the accessory device. Upon successful authentication of the accessory device, the host device may authorize the accessory device for power exchange interactions with the host device. The host device may then draw supplemental power from a power source associated with the authorized accessory device, such as a battery or power adapter. The host device may also enable the accessory device to obtain and use power supplied by the host device in some scenarios. Power exchange between a host device and an authorized accessory may be managed in accordance with capabilities of the accessory device that are identified during authentication.

    摘要翻译： 描述了附件设备认证技术。 在一个或多个实施例中，检测附件设备到主计算设备的连接。 响应于检测，可能发生认证序列以验证附件设备的身份和/或能力。 在附件设备成功认证后，主机设备可以授权附件设备进行与主机设备的电力交换交互。 然后，主机设备可以从与授权的附件设备（例如电池或电源适配器）相关联的电源中抽取补充电力。 在某些情况下，主机设备还可以使附件设备能够获得和使用由主机设备提供的功率。 可以根据在认证期间识别的附件设备的能力来管理主机设备和授权配件之间的电力交换。
