USB : Overview    USB Is Like A Railroad  

Most books on USB start out with all sorts of heart-stopping detail that make our eyes glaze over right away.

We figure you only want to learn enough USB to get your job done (but get it done right), so we’re going to take a different approach here. We’ll start off describing USB by an analogy. Occasionally, we’ll slip in a real USB term in parentheses, to show which part of our analogy corresponds to which term in the USB world.
