RE: Issue is why consumers have to worry?

When you say that USB isn't "universal" I think that's a quibble over a marketing term that has no meaning. I suppose it could be a veiled reference to "universal Turing machine" which might not be a term with which you are familiar.
As to USB not "working" this is a category error. The USB is, first and foremost, a technical specification which provides physical, electrical and logical details of how devices can communicate. It is sufficiently general, if not completely "universal" and as such can be used to do many things, some of which can be stupid. In addition, and this is my main beef with USB, it is quite complicated and so these implementations (primarily inside specialized chips) almost certainly have bugs and limitations. In addition, vendors take these chips and butcher putting them into computer systems. But the same can be said of simpler interfaces, e.g. SPDIF where people use the wrong impedance connectors.
I never had any trouble with carburetors. I learned how to tune the dual Weber carburetors on my Lotus Elan by ear and nose. Carburetors became unmanageably complex only after absurd government regulations were put in place. I've had many more problems with the electronic fuel injection systems that replaced them.
