Connect to HidDevice with UsbDevice class in UWP app

tomvangaever

Hi,

I'm using the stm32f746g-discovery board with the Keil USB HID example. I can connect to the USB HID device with a UWP app using the HidDevice class.
Is it also possible to use the UsbDevice class to connect to the board when using the Keil USB HID example? I want to try to use interruptOut to connect to the board and this is only possible with the UsbDevice class.

The UWP app I made with the UsbDevice class does not seem to connect to the USB of the discovery board (no problem with the HidDevice class UWP app).

Am I trying something that is impossible or am I doing something wrong with the connection?

I'm using the example code from Microsoft to connect:

private async void OpenDevice()
    {
        UInt32 vid = 0x045E;
        UInt32 pid = 0x0611;

        string aqs = UsbDevice.GetDeviceSelector(vid, pid);

        var myDevices = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(aqs);

        try
        {
            usbDevice = await UsbDevice.FromIdAsync(myDevices[0].Id);
        }
        catch (Exception exception)
        {
            ShowStatus(exception.Message.ToString());
        }
        finally
        {
            ShowStatus("Opened device for communication.");
        }

    }

With the correct vid & pid (works with HidDevice class).

I'm new to USB implementation and trying to learn.

thx
