USB-IF Confusingly Merges USB 3.0 and USB 3.1 Under New USB 3.2 Branding

Cables currently qualified for USB 3.1 will now run at double the speed.

Yup - you'll just need a new computer, new peripherals, new hubs/docks... but you can re-use the cables. Gaia thanks you.

...and what is the major step forward in human understanding of electronics that makes this possible now, and not a few years ago when USB-C first came out? Unforeseen New advanced bleeding-edge signal processing techniques that allow more bandwidth to be wrung out of the humble twisted pair?

Nope - its because USB-C currently only uses half the available wires in the cable for USB 3.1 - USB 3.2x2 just uses the spare wires for a second USB 3.1 stream, so why the blinking flip didn't they do that from the get go of USB-C?

Its almost as if they deliberately held it back so the industry could sell another round of new computers, peripherals, hubs docks...

Much ado about nothing.

Once it ripples through marketingspace, the SuperSpeed branding will shield novice consumers from the 3.x renaming tomfoolery. (That’s the whole point, Juli.) They care only that the gizmo plugs in and works. Thanks to protocol auto-negotiation, that’s most of the time.

Most of the time? Tell that to those wondering why their USB-C cable isn't charging the device quickly (because the cable lacks QC or Power Delivery, and why not full 100 W). Or why the USB-C cable is limited to USB 2.0 speed. You can't tell any of that by looking at the connector nor cable.

Yes. And that’s with the replier was implying. My point is that 99% of the time, it works.

What you’re rightfully complaining about is a completely different issue that has nothing to do with what this article is talking about.

But USB 3.2 5GBPS can come in USB-A whereas I believe the 10 and 20GBPS variants are only USB-C. Not sure if there are any 5GBPS Type C cables/devices out there.
 
Other ideas for new USB names:

USB-HD
USB-One

Or just call it USB, but keep the standards djfferent and just don’t tell anyone what they are (like HDMI).

This is what happens when IT nerds think they are also good at marketing. Seriously WTF.
 
Could definitely use some faster sync speeds when syncing the iPhone and iPad Pro with iTunes on a MacBook Pro. As of now ports on a new MacBook Pro support Thunderbolt 3 but try syncing an iPhone or iPad Pro with iTunes and see how long that takes each time it needs to do a full backup before it sync everything.:eek:

Would be nice to cut times down from like 10 minutes to 1 minute.

USB 3.1g1 (aka 3.0) is 5 Gbps - single stream - over either USB3-A or USB-C cables
USB 3.1g2 is 10 Gbps - single stream (same wires, higher data rate) and, yes some PCs have USB3-A type ports that support this, but on Macs its only via USB-C.

The new USB 3.2 modes take advantage of the fact that a USB-C cable has extra wires to run two 'bonded' USB 3.1 streams down the same cable (a bit like TB2 did with TB1*), so:

USB 3.2 g1x2 is two USB3.1g1 5Gbps streams combined over a USB-C cable to give 10Gbps
USB 3.2 g2x2 is two USB3.1g2 10Gbps streams combined over a USB-C cable to give 20Gbps


(*TB1 propped up the bridge while TB2 dropped the TB4 mini-sub in the water to rescue the trapped divers from... wait, no...)

if they had waited just a month longer and announced on April 1, it would have been great.

The USB Implementers Forum (USB-IF), this week announced a rebranding of the USB 3.0 and USB 3.1 specifications, under the USB 3.2 specification. As outlined by Tom's Hardware, USB 3.0 and USB 3.1 will now be considered previous generations of the USB 3.2 specification.

Going forward, USB 3.1 Gen 1 (transfer speeds up to 5Gb/s), which used to be USB 3.0 prior to a separate rebranding, will be called USB 3.2 Gen 1, while USB 3.1 Gen 2 (transfer speeds up to 10Gb/s) will now be known as USB 3.2 Gen 2.

What used to be considered USB 3.2 will now be USB 3.2 Gen 2x2 because if offers twice the throughput speeds of USB 3.1 Gen 2, now USB 3.2 Gen 2. If that sounds confusing to you, you're not alone. Tom's Hardware made this handy chart that shows the new branding scheme compared to the older branding.

If the swap between USB 3.1 Gen 1 and Gen 2 to USB 3.2 wasn't confusing enough, each of these specifications also has a marketing term. The new USB 3.2 Gen 1 with transfer speeds up to 5Gb/s is SuperSpeed USB, while USB 3.2 Gen 2 with transfer speeds up to 10Gb/s is known as SuperSpeed USB 10Gbps. The USB 3.2 Gen 2x2 specification with transfer speeds up to 20Gb/s is known as SuperSpeed USB 20Gbps.

Introduced in 2017, USB 3.2 (now USB 3.2 Gen 2x2) uses two 10Gb/s channels for a total data transfer rate of 20Gb/s, a feature limited to USB-C cables because USB-C cables support multi-lane operations.

USB 3.2 Gen 2x2 devices aren't out in the wild yet, and it's not yet clear when the first ones will arrive. Apple is often an early adopter of new USB technology and USB 3.2 Gen 2x2 could potentially be supported by the next-generation Macs.

Should have renamed them USB XR, USB XS, and USB XS Max.

“Apple is often an early adopter of new USB technology” lol. This is the same company that for years wouldn’t update to USB3 so they could push the travesty that was early Thunderbolt.

Incorrect...Apple waited until Intel integrated it into the Ivy Bridge 700-Series PCH (Panther Point) and then released the 2012 MacBook Pros (Retina and non-Retina) using Ivy Bridge CPUs and PCHs. Apple tends to wait until Intel integrates certain technologies into their PCH before releasing an updated Mac. Having it integrated in to Intel's chipsets is a much safer and more successful strategy than if Apple had integrated a third-party USB 3 controller in terms of PCB space used, cost and licensing. It also guaranteed a certain amount of security as Intel tends to wait a while before implementing these things and as such, you are generally going to see better long term support in the end.

Thunderbolt 1 only shipped a year earlier...not sure why you think it was a travesty, other than the cost of devices was quite high, even compared to Firewire 800 peripherals. Again, you can thank Intel and their high licensing costs for that.
 
No agenda at the last USB-IF meeting it would seem. So a board member offers up this 3.2 nonsense as a joke and it gets adopted. The joke, as usual though, is on us.

So, the standardization team continues to work towards destroying standardization. At what point will they be complicit in proporietary cables for all manufacturers. Can’t wait for my Apple USB-C that only works on Apple devices.

Apple, Intel, Microsoft, HP: Working to destroy the dream of USB.

What's their motive?

When do you think we get to the "nuke it and start over" phase for USB?

Next version will still be SuperSpeed, but they'll rebrand the 3.2 specs as PokeySpeed. And the new one will be USB 3.1 Gen 4x4 AWD.

The USB-C port is getting pretty old too..
I think it’s time for USB-C2

Absurb, its USB-C2.1 which combines the standards of C and C2. Not to be confused with USB 2.1 which is not compatible with the new.. USB-C2.2.

This is so dumb. They already have a problem with consumers not understanding the difference, and they decide to keep changing it?
