Unable to connect to USB devices in uwp

Victor Chen 101

I tried to connect USB devices in uwp according to the instructions in MSDN, and also tried to download the sample provided by MSDN to connect devices, but I still couldn't connect to usb devices.

What is the possible cause of this problem? Any directions or suggestions?

Here is part of my code:

Package.appxmanifest:

  <Capabilities>  
    <DeviceCapability Name="usb">  
      <Device Id="vidpid:1532 0a14">  
        <Function Type="name:vendorSpecific"/>  
        <!--The following statement also tries-->  
        <!--<Function Type="classId:ff * *"/>-->  
      </Device>  
    </DeviceCapability>  
  </Capabilities>

C# code:

string aqs = UsbDevice.GetDeviceSelector(0x1532, 0x0A14);  
var finder =  DeviceInformation.FindAllAsync(aqs).GetResults();  
//finder.Count always equals 0

Additional, This is actually an Xbox gamepad, and I can see the device on the device manager. The device path is: \?Usb#vid 1532&pid 0a14#0000c96c27402af7#{guid}. but what makes me confused is that the driver is dc1-controller.sys, not Winusb.sys, and the inf is dc1-controller.inf.
And I can get the device ID using DeviceInformation.FindAllAsync(string.Empty), but using UsbDevice.FromIdAsync(item.Id) always returns null, I don't know why.
