If the descriptor Microsoft WinUSB Device present, the driver stack assumes that the device contains one or more OS feature descriptors and the data that is required to retrieve those feature descriptors. The value indicates the vendor code that the USB driver stack must use to Microsoft WinUSB Device the extended feature descriptor. The extended compat ID OS feature descriptor includes a header section followed by one or more function sections depending on whether the device is a composite or non-composite device.

The header section specifies the length of the entire descriptor, number of function sections, and version number. For a composite device, there are multiple function sections. The extended properties OS feature descriptor includes Microsoft WinUSB Device header section that is followed by one or more custom property sections.

The header section describes the entire extended properties descriptor, including its total length, the version number, and the number of custom property sections. Note that Microsoft WinUSB Device GUID is specified as a Unicode string and the length of the string is 78 bytes including the null terminator. AddReg section of your custom Microsoft WinUSB Device.

For example, provide an appropriate manufacture's name, the name of your signed catalog file, the correct device class, and the Microsoft WinUSB Device identifier VID and product identifier PID for the device. Also notice that the setup class is set to "USBDevice".

You can obtain the hardware ID for the function from the properties of the devnode in Device Manager. We recommened that you provide a universal INF.
