Remarks

The UsbDeviceDescriptor class does not include manufacturer, product, and serial number strings that are included in a device-defined descriptor. You can obtain those strings by using the Windows.Devices.Enumeration namespace. For information about a USB device descriptor, see the top portion of this topic: USB device descriptors.
