No one really expected USB to be used to power everything

Yeah, it's not like the U stands for Universal or something.

    Yeah, Universal Spower Bus. Sounds right. I was reading the "power" part emphasized in the comment you replied to. Prior to mass adoption by phone mfrs, USB wasn't powering all that much. You'd usually have 5v wall wart and cable ending in a barrel connector. Hate those things.

    The Universal Spower Bus

    sounds like an awesome transit vehicle!

    Let's take a ride!

    Edit: Spower is a contraction of Space and Power. Yes, you heard me right. It's running on spinfinite space power!

    And there you have it,

    The Universal Spower Bus:

    I'm not really sure what that means. The original A/B specification did not allow for much variable voltage. It's only universal in name, not in nature. There was absolutely no way to deal with high voltage devices, the cables were not adaptive.

    USB 4.0 specification allows for powering things like electrical drills. No way the original USB A/B specification can handle that.
