根据配件是否能够改变电源路径的电气特性，启用附件到主机设备的电源

Enable power from an accessory to a host device based on whether the accessory is able to alter an electrical characteristic of the power path
Abstract:
Methods, systems, and apparatus for enabling a power path between a power source and a host device via an accessory. A host device may send, to an accessory arranged within the power path, via a first data pin arranged in the host device, a request for an accessory identifier. The accessory identifier identifies the accessory. The host device may then determine whether the accessory identifier is received from the accessory within a specified period of time or whether a received accessory identifier is valid. If the accessory identifier is not received from the accessory within the specified period of time, or a received accessory identifier is not valid, the host device sends a new request for the accessory identifier to the accessory via a second data pin different than the first data pin.
Abstract(Chinese):

用于经由附件启用电源和主机设备之间的电源路径的方法，系统和装置。 主机设备可以通过布置在主机设备中的第一数据引脚向配置在功率路径内的附件发送对附件标识符的请求。 附件标识符标识附件。 然后，主机设备可以在指定的时间段内确定附件标识符是否从附件接收，还是接收的附件标识符是否有效。 如果附件标识符在指定的时间段内没有从附件接收到或者接收的附件标识符无效，则主机设备经由与第一数据不同的第二数据引脚向附件发送附件标识符的新请求 销。
