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.

This is a very same line of argumentation as producing inflated and slow programs using RAD tools and similar "nice and easy" stuff.

OK, this tends to be flame-ish, I admit.
