USB 3.0 and USB 3.1 Merged Under New USB 3.2 Branding→

Juli Clover, writing for MacRumors about the latest rebrand in USB spec land:

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.

It gets better though:

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.

Make sure to check out the comparison table on MacRumors to admire the full extent of these changes.

As someone who’s been experimenting with USB-C accessories compliant with the USB 3.1 spec over the past few months, I can’t even begin to stress how confusing for the average consumer all of this stuff can be. It took me days to wrap my head around the differences between the physical USB-C connector, the underlying specs it can support, and the DisplayPort compatibility mode – and I do this for a living. In my experience, if you’re looking to buy modern USB accessories compatible with an iPad Pro or MacBook Pro, you’re better off looking for a technical spec label rather than the “friendly names” such as “SuperSpeed”, which manufacturers often fail to mention in their spec sheets.

Until today, if you wanted to buy USB-C accessories supporting the highest data transfer rates on the 2018 iPad Pro, you had to look for devices compliant with USB 3.1 Gen. 2; with today’s rebrand, the 2018 iPad Pro supports USB 3.2 Gen. 2 for transfers up to 10 Gbps, but not the similarly-named USB 3.2 Gen. 2x2. I’m sure this is going to be so easy to explain to someone who’s looking for the “fastest” USB-C cable for their iPad Pro.
