    Type: HIDDescriptor
        Identifies the length of type of subordinate descriptors of a HID
        device. This particular type only supports one subordinate descriptor.

    Variables:
        bLength - Size of descriptor in bytes.
        bDescriptorType - Descriptor type (<HIDGenericDescriptor_HID>).
        bcdHID - HID class specification release number in BCD format.
        bCountryCode - Country code of the device if it is localized.
        bNumDescriptors - Number of subordinate descriptors.
        bDescriptorType0 - Type of the first subordinate descriptor.
        bDescriptorLength0 - Size in bytes of the first subordinate descriptor.
