+/// !Purpose
+/// 
+/// Mass storage %device driver implementation.
+/// 
+/// !Usage
+/// 
+/// -# Enable and setup USB related pins (see pio & board.h).
+/// -# Configure the memory interfaces used for Mass Storage LUNs
+///    (see memories, MSDLun.h).
+/// -# Configure the USB MSD %driver using MSDDriver_Initialize.
+/// -# Invoke MSDDriver_StateMachine in main loop to handle all Mass Storage
+///    operations.
