This is a great article that illustrates the power of a picture. I have spent a fair amount of time in the instrument control world, and USB has made me want to throw a keyboard across the room several times. It's unbelievable how something supposedly standardized is anything but. It is the most unreliable interface I have ever used. There are also products that allow you to take USB 2.0 and USB 3.0 over fiber. You would think that such a product that claims USB 3.0 support, which is supposedly backward compatible with USB 2.0, would work with USB 2.0 devices, but usually not. I missed the fine print a few times and wasted some budget by making the mistake of thinking standards mattered.
