  Are you looking at 3.0, 3.2, 4.0? These are revisions of USB - the higher, the faster.

    Except for USB 3.2 gen 2, which can in some cases be slower than USB 3.2 gen 1, formerly known as USB 3.1.

    And USB 4, which defines two different possible operating speeds, one of which is equal in speed to USB 3.2 Gen 2x2 (not faster than it)

    And USB 4 Version 2 (lord help me) which defines a mode in which the upstream speed is halved in exchange for faster downstream speeds.

      I’ll upvote you for the info and the correction, but, in context of the question and questioner, I’m not sure it’s relevant.

      The higher the number, the newer the generation of USB. Mostly it means they have faster data transfer speeds and can output more power when charging devices.

    The higher… the fewer.

  I would assume it refers to how many USB port some devices has.

  3 or 4 USB ports on a device? Where are you seeing this?
