Normally if the USB device supports Microsoft OS descriptors, then it will allow Windows to automatically install the WinUSB driver. In this topic, you will learn about how a WinUSB device is recognized in Windows 8. Install WinUSB in the device's kernel-mode stack as the USB device's function driver instead of implementing a driver.

Typically, such devices Microsoft WinUSB Device not belong to well-defined USB classes such as Audio, Bluetooth, and so on, and require a custom driver. Therefore, your device must be installed under "USBDevice" setup class. About using the USBDevice class: Do not use the "USB" setup class for unclassified devices.
That class is reserved for installing controllers, hubs, and composite devices. Misusing the "USB" class can lead to significant reliability and performance issues. For unclassified devices, use "USBDevice".
Microsoft WinUSB Device In Windows 7, in addition to the preceding lines, you need to create these registry settings in the INF: However, the device class description is derived from the registry setting specified in your INF. If your computer is configured to get driver update automatically, WinUSB driver will get installed without any user intervention by using the new INF package.

That string is derived from Winusb. If there are multiple WinUSB devices, all devices get the same device description. In other words, when a device Microsoft WinUSB Device installed under "USBDevice" class, system queries the device for a device description and sets the Device Manager string to whatever is retrieved in the query.
In that case, the device description provided in the INF is ignored. Notice the device description strings: The string is provided by the USB device in its product string descriptor. The new class property is not supported on earlier versions of Windows. To have a customized device description on an earlier version of Windows, you have to write your own custom Microsoft WinUSB Device.
For information about the descriptors, see the specifications described here: Supporting extended feature descriptors In order for the USB driver stack to know that the device supports extended feature Microsoft WinUSB Device, the device must define an OS string descriptor that is stored at string index 0xEE. During enumeration, the driver stack Microsoft WinUSB Device for the string descriptor.
If the descriptor is 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 retrieve the extended feature descriptor. Set the value to the GUID you generated in step 2.

For example, provide an Microsoft WinUSB Device manufacture's name, the name of your signed catalog file, the correct device class, Microsoft WinUSB Device the vendor 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 Microsoft WinUSB Device you provide a universal INF.
INF files for devices in an installed class, whether a system-supplied device setup class or a custom class, must not include a ClassInstall32 section. Except for device-specific values and several issues that are noted in the following list, you can use these sections and directives to install WinUSB for any USB device.
These list items describe the Includes and Directives in the preceding. You should not modify these directives.
