Hello,

I am using C# to detect usb vsp com port for my ARM controller via usb port. My program has been working properly, but I can't get the descriptor on ARM controller because windows use universal serial device driver. I found item "bus reported device" in device manager to have controller descriptor, but when I use win32_PNPdevices to query it, I can't get this property, anybody has some solution?

    From this thread https://forum.lazarus.freepascal.org/index.php?topic=59729.0

    with Win32_PnPEntity and PnpClass = "Ports"

    (Device Manager calls SetupDi APIs (SetupDiGetClassDevs and so on)
