Unfortunately, HN is so bad at publicizing and making this easy. I spent years assuming others knew some magical tool I didn't, before realizing people just do everything manually and stick to the same unwritten style guide.
USB-IF has to be doing this to deliberately confuse end users, right? I get that it's a specification number, not a product name, but they have to know that this will only cause problems for customers trying to find the appropriate cable. Incredibly, their language usage specifications doc https://www.usb.org/sites/default/files/usb_3_2_language_pro... begins with this: > USB-IF emphasizes the importance and value of…
When I was growing up, we had USB, FireWire, and a couple size/speed variations. It was easy to understand and you could tell what a cable was by looking at it.
For people who grew up in this era, the current situation is super annoying. Perhaps the young people of today will view peripheral standards as some sort of super-obscure language that isn’t intended to be decipherable by laymen?
> 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." Does anyone care about Gbps for USB? I've never hit the bandwith limitation on USB and see USB type-C as just an annoyance making me buy new cables. > And 20Gb/s devices w…
> Does anyone care about Gbps for USB? I've never hit the bandwith limitation on USB and see USB type-C as just an annoyance making me buy new cables. External SSDs are probably the only time it matters, or even multiple drives connected through a USB hub.
I've also run into this using external ethernet adapters, which I still want when I'm copying large files or streaming video via airplay or steam. My last 3 laptops were missing inbuilt ethernet ports. USB 2, while much faster than the wifi speeds available at the time, only supports half the bandwidth of gigabit ethernet.

I don't think there was ever a USB spec that allowed you to skip the data lines. That is purely a chinese cost optimization. Meanwhile, the confusion with USB 3 (C?) is designed in .
You say cost optimization, I say safety feature.

So is there going to be a generation of young people who grow up thinking that all peripherals are USB, and that the naming system is so complicated/nonsensical that it isn’t even worth trying to figure it out? When I was growing up, we had USB, FireWire, and a couple size/speed variations. It was easy to understand and you could tell what a cable was by looking at it.

Muddying the waters is a diabolically genius way of attacking the generic cable manufacturers.

I'm mostly serious, though I really don't know why 1×2 exists and why you'd build a part that supports it but not 2×2 (or, alternatively, that supports it instead of 2×1, which is, but for a name change, an older standard with the same nominal bandwidth), and the 2×2 will also support 2×1. But maybe there is an electrical engineering reason why it might be practical to do 1×2 but not 2×1 in some device.
1x2 requires lower frequency electrical signals I suspect? That might be preferable in some scenarios. Still insane.
Here is a helpful chart of USB versions and their connectors: https://preview.redd.it/s9dun6a1xmpz.png?width=960&crop=smar... e.g. USB 3.2 has the same connector as USB-C edit: I personally care far more about the connector than exact specs of each version
hopefully usb-c connectors are tougher then micro-usb's

And A is always the same socket regardless of version while B is not. It's a mess.
> And A is always the same socket regardless of version Even this is technically incorrect: USB-3 A-type sockets, though backwards compatible for f/m and m/f connecting with USB-2, have 5 more contacts compared to USB-2 type A sockets.
