USB 3.0 and USB 3.1 merged under new USB 3.2 Branding – MacStories



Juli Clover, writes for MacRumors about the latest rebrand in USB-specific countries:

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 described by Tom's Hardware USB 3.0 and USB 3.1 will now be considered as previous generations of the USB 3.2 specification.

Continue, USB 3.1 Gen 1 (transfer rates up to 5Gb / s) used to be USB 3.0 before a separate rebranding, will be called USB 3.2 Gen 1, while USB 3.1 Gen 2 (transfer rates up to 10Gb / s) will now be known as USB 3.2 Gen 2.

It gets better though:

If switching between USB 3.1

Gen 1 and Gen 2 to USB 3.2 was not confusing enough, each of these specifications also has a marketing time. The new USB 3.2 Gen 1 with transfer rates up to 5 Gb / s is SuperSpeed ​​USB, while USB 3.2 Gen 2 with transfer rates up to 10 Gb / s is known as SuperSpeed ​​USB 10Gbps. USB 3.2 Gen 2×2 specification with transfer rates up to 20Gb / s is known as SuperSpeed ​​USB 20Gbps.

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

As someone who has experimented with USB-C accessories that are compatible with the USB 3.1 specification in recent months, I can "Don't even begin to stress how confusing the average consumer all these things can be. It took me days to wrap my head around the differences between the physical USB-C connector, the underlying specifications it can support, and the DisplayPort compatibility mode – and I do this to live in. In my experience, if you want to buy modern USB accessories compatible with an iPad Pro or MacBook Pro, it is better to look for a technical specification code than the "friendly names" such as "SuperSpeed", which manufacturers are often not mentioned in their specification sheet.

To date, if you wanted to buy USB-C accessories that support the highest data transfer rates of the 2018 iPad Pro, you had to look for devices that are compatible with USB 3.1 Gen. 2; With today's rebrand 2018 iPad Pro USB 3.2 supports Gen. 2 for transfers up to 10 Gbps, but not the same name USB 3.2 Gen. 2×2. I'm sure this will be so easy to explain to someone looking for the "fastest" USB-C cable for their iPad Pro.
