Write and Read Memory Stick with Arduino Host Shield

Well, I’ve bought an Arduino Host Shield. Thus, my question is anybody knows how to write/read a file from a USB memory stick connected in this shield?

About two years ago I wrote a library, UsbFat for USB mass storage devices. It works with the Arduino ADK so may work with the host shield.

Few people use USB storage devices with Arduino so I have not updated it recently. I tested it with a recent version of the IDE a few months ago.

Thanks for your answer, the library works perfectly. One question more, this library can be used with Marlin Firmware ?
