No, I don't know where you found those, but they aren't USB standards. There's USB 1.0, USB 1.1, USB 2.0, and soon USB 3.0, that's it.
Then somewhere along the line they invented USB hi-speed and USB full speed to represent USB 1.1 and USB 2.0 respectively.
Are these different standards/data transfer rates, are they all high speed connections? I've looked around a heap of places yet no one is willing to go into further detail about what this means... CAN ANYONE HELP PLZ!
