+/// !!!Purpose
+///
+/// This directory provides definitions, structs and functions for a USB Audio
+/// Class device - USB audio-looprec demo, to implement an USB desktop speaker
+/// which echos audio stream back to host.
+///
+/// !!!Contents
+/// There are two things for the implement of the audio-speaker device driver:
+/// - Implement the audio-looprec driver structs and functions for the device,
+///   to initialize, to handle audio class specific requests and dispach
+///   standard requests in USBD callbacks, to read/write through assigned USB
+///   endpoints,
+/// - Create the audio-speaker device's descriptors that should be passed to
+///   the USBDDriver instance on initialization, so that the host can 
+///   recognize the device as a USB audio "desktop speaker" device.
+///
+/// This project is simply addon to the audio speaker demo. For more
+/// information, please refer to "USB Audio Speaker Device".
