Please note, if you plan to use USB keypad to control directions, be aware that some complex
keypads, especially those embedding other functions such as an embedded display or
touchpad, may in fact be a complex USB device, e.g. embedding an USB HUB, and these may
not work with ARCO. Simple and cheap USB keypads work well.
