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.
