Hi, I've inherited one of these boards ( second hand) , and its the first time I've come across one.
I can program it via ICSP and that works fine, but the USB (square one) does not respond, nothing happens when plugged into my computer, nothing in device manager, no sound ,although the board powers through it .
I'm guessing there is a fault with the board, but would like to be sure. I've not tried bootloading it (unsure which bootloader to use)
As I'm unfamiliar with this board is this a setting problem or something to do with the "Android" USB socket or is there a way to program it via this other socket.
any help appreciated.
Paul
