/// !Purpose
/// 
/// Constants for manipulating USB audio-specific descriptors.
///
/// !Usage
///  
/// - For a USB device:
///     -# When declaring an Audio-specific descriptor, use the descriptor types
///        and subtypes defined in this unit (see "Audio descriptor types" and
///        "Audio descriptor subtypes").
