    Additionally, USB 3.0, 3.1 and 3.2 labels provide no information on the speed. Rather, “Gen 1” means 5Gb/s, Gen 2 means 10 and Gen 2×2 means 20Gb/s. These “Gen” labels are seldom found on products however.

    So for example USB 3.2 Gen 1 is 5Gb/s while USB 3.1 Gen 2 is 10Gb/s

      The dear people at the USB Forum should be rewarded with the Nobel prize in namology for their clear, superior and non-confusing naming scheme and naming process that even the nerdiest of nerds can’t follow.

          Behind the scenes, here’s what those labels correspond to:

          • USB 5Gbps: USB 3.0 and 3.1 Gen 1

          • USB 10Gbps: USB 3.1 Gen 2, 3.2 Gen 2×1, and 3.2 Gen 1×2

          • USB 20Gbps: USB 3.2 Gen 2×2

          • USB 40Gbps: USB4’s initial version as currently shipping

          That’s cool. But even though it finally adds simplicity, it’s still yet another renaming of the same things.

          Here’s a snippet from an article from 2019:

          The upcoming 20 Gb/s USB 3.2 connection, which offers twice the speeds of the previous iteration, will be known as ‘USB 3.2 Gen 2x2’. Its predecessor, ‘USB 3.1’ will be rebranded to ‘USB 3.2 Gen 2’, while ‘USB 3.0’, which ran at 5 Gb/s speeds, will be termed ‘USB 3.2 Gen 1’.

          Reading that I want to shoot myself, and even the latest change, which probably is a good one, drives me slightly mad due to the history of renaming everything so many times.

            the history of renaming everything so many times.

            Every time a new USB spec comes out the version number goes up. A new spec comes out because they add more features. The spec is a whitepaper that explains all the features. It’s a “The King is dead, long live the king!” situation.

            If you just never used the version numbers to mean something that they never meant (transfer speeds) then literally none of this is confusing.

            They’ve officially renamed the transfer speeds one time after people made a big huff. here’s how they changed:

            • USB SuperSpeed -> USB 5Gbps

            • USB SuperSpeed 10Gbps -> USB 10Gbps

            • USB SuperSpeed 20Gpbs -> USB 20Gbps

            And If you can’t follow along with that, I’m really, really sorry. There’s not much I can do from a internet discussion board. XD

              Yes, I am the only one confused. It’s not like half the tech internet blew a gasket over how confusing and bad the renaming of the generations were. Just me. I guess I should just read the whitepapers of every standard going forward, silly me.

                Well if there’s anything I expect from the new-cycle masses, it’s rationality.

                Heaven forbid, we try and do better!

                I guess I should just read the whitepapers of every standard going forward, silly me.

                You don’t have to read whitepapers to know the difference between Ethernet, CAT6 and RJ45 even if your grandpa doesn’t know the difference.

                It’s not too much to expct the “nerds” to know the real names of PAN connections, too.

      All so sales people can slap on a 3.2 sticker over the 3.1 that was on top of the 3.0 sticker…

      Correct.

      USB X.X is the name of the technical whitepaper that describes the standard.

      For a long time, USB had three transfer rates. The first legacy speed (slowest) was hardly ever used. The Second was called “Full Speed” and the fastest was called “Hi-speed”. Because people could not remember which if these two were faster, they referred to the whitepapers in which they were introduced.

      When later versions of USB were introduced people have tried to continue this mental “shortcut” and have caused themselves nothing but confusion.
