People already get the names wrong, so the USB group has doubled down on bad naming.

https://arstechnica.com/gadgets/2019/02/usb-3-2-is-going-to-make-the-current-usb-branding-even-worse/

USB 3.0 was straightforward enough. A USB 3.0 connection ran at 5Gb/s, and slower connections were USB 2 or even USB 1.1. The new 5Gb/s data rate was branded "SuperSpeed USB," following USB 2's 480Mb/s "High Speed" and USB 1.1's 12Mb/s "Full Speed."

But then USB 3.1 came along and muddied the waters. Its big new feature was doubling the data rate to 10Gb/s. The logical thing would have been to identify existing 5Gb/s devices as "USB 3.0" and new 10Gb/s devices as "USB 3.1." But that's not what the USB-IF did. For reasons that remain hard to understand, the decision was made to retroactively rebrand USB 3.0: 5Gb/s 3.0 connections became "USB 3.1 Gen 1," with the 10Gb/s connections being "USB 3.1 Gen 2." The consumer branding is "SuperSpeed USB 10Gbps."

What this branding meant is that many manufacturers say that a device supports "USB 3.1" even if it's only a "USB 3.1 Gen 1" device running at 5Gb/s. Meanwhile, other manufacturers do the sensible thing: they use "USB 3.0" to denote 5Gb/s devices and reserve "USB 3.1" for 10Gb/s parts.

USB 3.2 doubles down on this confusion. 5Gb/s devices are now "USB 3.2 Gen 1." 10Gb/s devices become "USB 3.2 Gen 2." And 20Gb/s devices will be... "USB 3.2 Gen 2×2." Because they work by running two 10Gb/s connections along different pairs of wires simultaneously, and it's just obvious from arithmetic that you'd number the generations "1, 2, 2×2." Perhaps they're named for powers of two, starting with zero? The consumer branding is a more reasonable "SuperSpeed USB 20Gbps."

Forget USB 3.2: Thunderbolt 3 Will Become the Basis of USB 4 23 comments

USB 3.2 Gen 2×2 isn't even my final form:

Fulfilling its 2017 promise to make Thunderbolt 3 royalty-free, Intel has given the specification for its high-speed interconnect to the USB Implementers Forum (USB-IF), the industry group that develops the USB specification. The USB-IF has taken the spec and will use it to form the basis of USB4, the next iteration of USB following USB 3.2.

Thunderbolt 3 not only doubles the bandwidth of USB 3.2 Gen 2×2, going from 20Gb/s to 40Gb/s, it also enables the use of multiple data and display protocols simultaneously. We would expect the USB4 specification to be essentially a superset of the Thunderbolt 3 and USB 3.2 specifications, thus incorporating both the traditional USB family of protocols (up to and including the USB 3.2 Gen 2×2) and the Thunderbolt 3 protocol in a single document. Down the line, this should translate into USB4 controllers that support the whole range of speeds.

Lost? Frightened? Confused? Good!

    And there's a USB-C connector, well I think its just a connector... it's part of both the 3.1 and 3.2 specs according to wikipedia: https://en.wikipedia.org/wiki/USB-C [wikipedia.org] so does that mean they retarded usb-3-micro thing is gone finally?

          Um . . . there WAS a Mac OS 9. It was the final beloved version of the Classic Mac OS. After it came the abomination popularly known as OS X with an obsession on cats.

          Spend less time fixating on skipping over nine and spend more time obsessing on the number 10, but label it X.

          Mac OS X will be the last one.

          Windows 10 will be the last one. Microsoft: please change the name to Windows OS X.

    ...to point and laugh. The marketing geniuses that came up with this need to be ridiculed so that they avoid ridicule next time.

    I'm less than impressed that is it possible to buy cables with a USB2 Type A (NOT 'Type A SuperSpeed') plug [wikipedia.org] on one end and a USB3 Type C plug [wikipedia.org] on the other that cannot be used to charge a device with a USB3 socket. Especially as the cable I bought is marked on its packaging that it is a charging cable, not a data cable.

    EN USB Charging cable. The charging cable should only be used for adapters with the right capacity, in this case max. 2.4 A."

    It does not charge the mobile phone I bought the cable to use with.

It helps promote e-waste while not running afoul of EU laws designed to eliminate e-waste that was caused by every phone needing a different custom charger. Your old cables and adapters can be ground into a new powdered food additive marketed as being high tech.

    In order to eliminate confusion and not cause any more damage to the USB branding, I propose that the next version be named USB 5G!

    5G is the best! Just ask AT&T about its fictional 5G!

    And this won't screw up the USB branding even more. Nope! Nosiree!

    Everyone can tell it is better because it's named 5G!

        You sir need to look more carefully at USB-C. It goes both ways!

        The USB-C cable has two male ends. The devices (phone, laptop, desktop doc, wall wart charger, etc) all have female connectors.

        Since both ends of the cable are male, you first of all don't have to worry about which end of the cable goes where.

        There isn't this distinction between "host" and "device". You can plug two phones together. (Both phones have female connector, cable has two male connectors.)

        Or you can plug two laptops together. Or plug a phone and laptop together. Or a phone and a charger. Furthermore, you CAN actually use a laptop charger with a phone, or a phone charger with a laptop. The devices negotiate with the charger how much juice they will get. If you use a phone charger on a laptop, you get a nice warning that it will not rapidly charge. Phone charger blocks are 15W and laptop charger blocks are 45W. I would think that all I really need are laptop charger blocks, but they are more expensive than a phone charger brick.

        When you insert the male cable connector into the female device connector, you can insert it either way up. No more having to flip the cable over because you tried to insert it the wrong way.

    I hear you are having issues with brand confusion; I think that we can generally agree that you have no idea how to name things.
    How about we make a small change and simplify things. I propose we change the naming to something we can all agree on; it is the speed that matters.

    USB 3.0 / USB 3.1 Gen 1 / USB 3.2 Gen 1 Should now be referred to as USB 3 - 5
    USB 3.1 / USB 3.1 Gen 2 / USB 3.2 Gen 2 Should now be referred to as USB 3 - 10
    USB 3.2 2x2 Should now be referred to as USB 3 - 20

    USB 3 - 5 supported plug types A / C
    USB 3 - 10 supported plug types A / C
    USB 3 - 20 supported plug types C

    Simple elegant and full of useful information.

    Note further developments are easily managed e.g.
    USB 3 - 40 supported plug types C / D
    USB 4 - 100 supported plug types D
