Besides using a mouse, the USB host shield 2 can also access a ash drive through a serial terminal emulator such as hyperterminal. The ash drive must be in FAT32 format for it to be accessible. The manual provided by ATMEL is also provided in the same folder as this manual with the filename “Commands List.html”.
