I am looking for more information on how winusb is used as a filter for a umdf driver project. I downloaded the c# winusb application and the pinvoke command WinUsb_Initialize fails to populate the endpoints even though the device is detected and I have the handle.
Here is the inf file I used for the usb driver installation;
