是否可以将 PnpObjectType_DeviceInterface 添加到 UWP Package.appxmanifest <DeviceCapability>？

Question

我的 Win32 应用程序通常通过 USB 接口与串行设备通信。多年来，出于诊断和开发目的，我一直使用创建串行环回接口的 Com0Com 实用程序。我现在正在编写我的应用程序的 UWP（非商店）版本。

Com0Com端口在调用时可见

// Construct AQS String for all serial devices on system
Platform::String ^serialDevices_aqs = Windows::Devices::SerialCommunication::SerialDevice::GetDeviceSelector();

// Identify all paired devices satisfying query
return Windows::Devices::Enumeration::DeviceInformation::FindAllAsync(serialDevices_aqs);

添加查看从我获取的串行设备列表中获取的 com0com 端口的 device_ID 值

[Id] = L"\\?\com0com#port#CNCA1#{86e0d1e0-8089-11d0-9ce4-08003e301f73}"
[Type] = PnpObjectType_DeviceInterface (1)
[1] = {L"System.Devices.DeviceInstanceId" = L"com0com\port\CNCA1"}

如果我根据

修改 Package.appxmanifest 文件

https://docs.microsoft.com/en-us/uwp/schemas/appxpackage/appxmanifestschema/element-devicecapability

<Capabilities>
    <DeviceCapability Name="serialcommunication">
        <Device Id="any">
            <Function Type="name:serialPort" />
        </Device>
        <!-- added below -->
        <DeviceCapability Name="86e0d1e0-8089-11d0-9ce4-08003e301f73"/>
    </DeviceCapability>
</Capabilities>

唉

return Concurrency::create_task(SerialDevice::FromIdAsync(device->Id), childToken)
        .then([this](SerialDevice ^serial_device)

始终将 null 传递给任何选定 com0com 端口的 lambda 函数 null。

我是不是做错了，或者在 UWP 约束下是不可能的。

Am I doing this incorrectly or is it not possible within the UWP constraints.

很遗憾，FromIdAsync() method. According to this document 似乎不支持您的情况：

System-internal or on-chassis serial ports may be enumerated by DeviceInformation.FindAllAsync(), but cannot be opened by SerialDevice.FromIdAsync() because they currently are not supported. However, serial ports connected over USB, such as on USB-to-Serial cables are supported.

com0com你这里说的好像是虚拟串口驱动，不是USB连接的，可能不支持
