    • A peripheral device is connectable to a computer having one of a first interface and a second interface. The first interface communicates with the peripheral device over a differential data connection having a first data conductor and a second data conductor. The second interface communicates with the peripheral device over a clock conductor and a single ended data connection which includes a data conductor. The peripheral device has first and second communication conductors configured for connection to the first and second data conductors in the differential data connection when the computer includes the first interface and is configured for connection to the first data conductor in the single ended data connection and the clock conductor when the computer is provided with the second interface. The peripheral device includes an interface detection component coupled to the first and second communication conductors and configured to detect which of the first and second interfaces the peripheral device is connected to. The peripheral device also includes a controller component configured to communicate between the peripheral device according to a protocol corresponding to the detected interface.
    • 外围设备可连接到具有第一接口和第二接口之一的计算机。 第一接口通过具有第一数据导体和第二数据导体的差分数据连接与外围设备进行通信。 第二接口通过时钟导体和包括数据导体的单端数据连接与外围设备进行通信。 外围设备具有第一和第二通信导体,当计算机包括第一接口并被配置为连接到单端数据连接中的第一数据导体和时钟时,配置用于在差分数据连接中连接到第一和第二数据导体 当计算机配备有第二接口时, 外围设备包括耦合到第一和第二通信导体并被配置为检测外围设备连接到的第一和第二接口中的哪一个的接口检测组件。 外围设备还包括控制器组件,其被配置为根据与检测到的接口对应的协议在外围设备之间进行通信。
