/// !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.
