Hi there.
First of all I have asked this question in arduino.cc forum but I am not getting any answer. So, I am gonna ask the same thing here.
I have build an Arduino on breadboard with just a crystal oscillator and reset switch. It works fine with a lot of example codes. However, I am not sure if it will work with a USB Host Shield. Will it work? Will it nor? Or do I need to add some circuitry? I am planning to buy the USB Host Shield from Cytron but it would be best if I can confirm whether it will work or not first(budget issue). Perhaps someone can try it for me?
