UWP app cannot find/connect to USB device

Question

I am trying to make a UWP app which connects to a USB device and then executes a series of commands, like retrieving data from the internal sensor (think of an accelerometer

Answer 1

This is how to connect to a WinUSB device on UWP.

public async Task> GetConnectedDeviceDefinitions(uint? vendorId, uint? productId)
{
    var aqsFilter = "System.Devices.InterfaceClassGuid:=\"{DEE824EF-729B-4A0E-9C14-B7117D33A817}\" AND System.Devices.InterfaceEnabled:=System.StructuredQueryType.Boolean#True AND " + $" System.DeviceInterface.WinUsb.UsbVendorId:={vendorId.Value} AND System.DeviceInterface.WinUsb.UsbProductId:={productId.Value}";

    var deviceInformationCollection = await wde.DeviceInformation.FindAllAsync(aqsFilter).AsTask();

    //TODO: return the vid/pid if we can get it from the properties. Also read/write buffer size

    var deviceIds = deviceInformationCollection.Select(d => new DeviceDefinition { DeviceId = d.Id, DeviceType = DeviceType.Usb }).ToList();
    return deviceIds;
}
