/// !!!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 "USB Audio descriptor types"
///        and "USB Audio descriptor subtypes").
