Windows Phone 7或8?

Windows Phone 7 or 8?

连接时的USB被抽象为网络连接.您没有直接访问USB的权限.我建议根据您要完成的工作使用Wifi或蓝牙. Windows Phone不能用作USB主机设备.

The USB when connected is abstracted as a network connection. You dont have direct access to the USB. I would recommend using Wifi or bluetooth for that depending on what you are trying to accomplish. Windows Phone can't be used as a USB host device.
