This program is an example of of using the MSCUSBHost code with a raw build of ELM Chan Fat Fs. This was done to add both Long File Name Support along with proper time/date stamps (assuming you have a battery hooked up to keep time). This code exposes the Chan API (see main.cpp) and is NOT a c++ class: http://elm-chan.org/fsw/ff/00index_e.html The diskio.c file has the mapping needed to link the filesystem to the MSC stuff
