-/* Introduction
- * ------------
- * The USBMSD implements the MSD protocol. It permits to access a memory chip (flash, sdcard,...)
- * from a computer over USB. But this class doesn't work standalone, you need to subclass this class
- * and define virtual functions which are called in USBMSD.
- *
- * How to use this class with your chip ?
- * --------------------------------------
- * You have to inherit and define some pure virtual functions (mandatory step):
- * - virtual int disk_read(char * data, int block): function to read a block
- * - virtual int disk_write(const char * data, int block): function to write a block
- * - virtual int disk_initialize(): function to initialize the memory
- * - virtual int disk_sectors(): return the number of blocks
- * - virtual int disk_size(): return the memory size
- *
- * All functions names are compatible with the fat filesystem library. So you can imagine using your own class with either
- * USBMSD or a fat filesystem library.
- *
- * Once these functions have been defined, you can call connect() (at the end of the constructor of your class for instance)
- * of USBMSD to connect your mass storage device ;)
