List UART -> COM converter in Windows Device Portal

问题

I have Raspberry Pi 3 plate with connected USB to UART (COM) converter.
The power led on the USB stick is ON.
I can not find the converter in Windows Device Portal.
In both: connected and disconnected states I see just two UART related records in Device Manager:

        (ID:ACPI\BCM2835\0, Class:System, Manufacturer:Microsoft, StatusCode:25165834)
        >BCM283x Mini UART Serial Device
        (ID:ACPI\BCM2836\0, Class:Ports, Manufacturer:Microsoft, StatusCode:25182218)
        >ARM PL011 UART Device Driver
        (ID:ACPI\BCM2837\4, Class:System, Manufacturer:Microsoft, StatusCode:25165834)

Also I use git diff between saved device lists and there is no difference between the case I connect USB stick and disconnect it.
Where can I see the device in the list?

UPDATE

Here I print all found devices:

First you need make sure your USB to UART (COM) converter is supported on Windows IoT Core. Please check the hardware compatibility list. The CP2102 USB 2.0 to TTL Module Serial Converter is supported.

I use CP2102 USB to UART Bridge Converter and it also works. Use the SerialUART sample can list two device: one is on-board PL011 UART Device and the other is mine.
