推荐答案

亲爱的朋友，

您是否使用过github的官方串口UART示例： 

Did you use the official Serial UART Sample from github: 

https://developer.microsoft.com/en-us/windows/iot/samples/serialuart

https://developer.microsoft.com/en-us/windows/iot/samples/serialuart

如果你试试这个，你会发现在此示例中连接的USB-to-TTL线缆的设备ID以'\？\USB #VID _ ****'开头。机载串行端口以  '\？\ ACPI＃VID _ ****'开头。 

If you try this out, you will find that the device ID for the USB-to-TTL cable connected in this example begins with ‘\?\USB#VID_****’. And the on-board Serial Port begins with  ‘\?\ACPI#VID_****’.
