I have been as frustrated as anyone by trying to plug in USB plugs both ways. Or by finding that USB plugs make a rather neat fit in RJ45 jacks. But really, looking back on the history of common connectors (DB plugs, DIN plugs, 10BASE2, etc.), USB looks really simple, safe, cheap, reliable, and easy-to-use. I've never had a USB socket go bad. I've never shorted out any equipment by brushing a USB plug with a conductive object. I've never needed to clean a USB connector to get it to work properly. But all those things have happened to me with USB's predecessors.
