    Type: USBDeviceDescriptor
        USB standard device descriptor structure.

    Variables:
        bLength - Size of this descriptor in bytes.
        bDescriptorType - Descriptor type (<USBGenericDescriptor_IAD>).
        bFirstInterface - Interface number of the first interface that is 
                          associated with this function. 
        bInterfaceCount - Number of contiguous interfaces that are 
                          associated with this function. 
        bFunctionClass - Class code (assigned by USB-IF).
        bFunctionSubClass - Subclass code (assigned by USB-IF).
        bFunctionProtocol - Protocol code (assigned by USB-IF)
        iFunction - Index of string descriptor describing this function.
