+ * \section Usage
+ * 
+ * -# Enable and setup USB related pins (see pio & board.h).
+ * -# Configure the memory interfaces used for Mass Storage LUNs
+ *    (see memories, MSDLun.h).
+ * -# Instance the USB device configure descriptor as
+ *    MSDConfigurationDescriptors or MSDConfigurationDescriptorsOTG defined.
+ *    Interface number should be 0.
+ * -# Configure the USB MSD %driver using MSDDriver_Initialize.
+ * -# Invoke MSDDriver_StateMachine in main loop to handle all Mass Storage
+ *    operations.
