There's nothing wrong with using USB on a backplane or motherboard, and in fact it makes a lot of sense for things like keyboards and mice. I don't share this view. USB is unnecessarily complicated for a task where a simple serial protocol would more than suffice. It only makes sense in a world where complicated albeit potentially (and also really) buggy drivers for complex USB devices are more readily available than say a simple I2C device driver. Oh, come on, Jan, you're being silly. USB drivers for keyboards and mice are certainly standard and after ten years, debugged. If they use the same keyboard interface chip that's used in a standard external USB keyboard, one can also be assured that it, too, works. Using USB instead of, say, I2C, means that NO host software or drivers has to be written. -a |
