title: USB port to detect "close" or "open" switch
body: <p>I need to make a program that would play a sound as I press a push button switch. My idea is to use the USB port, and that if I short 2 wires from it (like for example the data+ and data-), the program would play a sound repeatedly while the 2 wires are shorted. Is my idea possible and simple to do? Can you please help me do it using VB? Thanks a lot for any help.</p>
