ACAB but expressed in USB connector types (that funky shaped one on the right was a short lived USB connector type B). I only had like one peripheral, a scanner, that used it.
short lived
A printer I bought two years ago, a DAC a month ago. Its definitely not short lived
Yeah, AFAIK all printers still have these
Yeah I always call it the printer USB port. I wonder why it’s so popular there? Maybe it’s the USB connector that is hardest to break or pull off by accident?
My understanding it's the other end of a one way USB cable. Normally the cable is attached like your mouse or keyboard, or commonly these days USB C, but if you are plugging in USB and it's not USB C but the cable unplugs at either end, one will be USB A and the other USB B so you can't put it in backwards like you could if they both has USB A.
Early android smart phones used USB B micro or mini, but printers have no need to keep the plug small.
Wild, TIL.
A screen I bought recently has this for the integrated USB hub, I think?
Every monitor with a USB hub and every printer I’ve owned for the last 20 years has had one. It’s used to differentiate USB directionality, for example which side is upstream or the “host device” and which side is meant to plug into the computer.
They’re moot now with USB C which is bidirectional; USB-A male to USB-A male is dangerous and not compliant with the USB specification, so they’d use USB-B on one side.
Anything non-portable that you plug in to a computer with a USB-A connection is supposed to have a USB-B on the other end if the cable is removable.
I have a lot of music gear with USB-B connectors on them
And then you have the cursed non standard USB A to USB A
My cheap knockoff elgato has that and it still creeps me out when I use it lol.
Same. Music gear (although my recent stuff has started going C), printers and scanners since USB became a standard, older networking hardware, older external hard drives (most of them before USB 3.0), and every piece of medical equipment I've ever dealt with. It was ubiquitous from the time USB started in the 90s until USB C got popular after 2014.
until USB C got popular after 2014
Nonono, USB-C isn't over a decade old.....

a short lived USB connector type B
Not short lived at all, it's literally one of the three standard connectors alongside A and C. USB is an inherently directional protocol, so one side if the host device and the other is the peripheral device. The difference between Type A and B plugs helped enforce that directionality. Prior to the C connector becoming the new standard regardless of direction, all USB cables had both a Type-A and Type-B connector. (A to A cables violate the spec, and are an abomination).
The miniUSB and microUSB connectors are both Type-B connectors, just physically smaller to accommodate smaller peripheral devices. There's also technically a mini-A and micro-A, but they're very uncommon since host devices are usually large enough for a full size plug, and now USB 3.0+ Type-C connections don't require a directional cable the same way.
I have a bunch of USB hubs that plug into a USB-A outlet and then give you USB-A outlets. Are these not cursed because they're a hub?
I also have a switchable USB hub from Amazon that lets you send your USB hub outlets to one out of four host devices. I use this to be able to have my mouse and keyboard plugged into my desktop or switch it to my laptop, if I have my laptop plugged into a USB dock.
That switchable USB hub uses USB-A to USB-A cables to connect the hub to the host devices. What cable should it use instead for this purpose? USB A to USB B? And the hub would have four USB-B inputs on the back?
To answer my own question, here is a expensive version of what I'm talking about, which uses USB-A to USB-B. https://www.startech.com/en-us/usb-hubs/hbs304a24a
And here is the cheap version I have from Amazon, over $100 cheaper which uses the cursed cable... https://www.amazon.com/dp/B0CHY8L11W/
Is there any risk of using the cheap A to A version?
So far the only downside I've seen is that the keyboard and mouse don't work super well in the UEFI screen maybe one time in 20. And sometimes the keyboard would disconnect in other contexts, but that seems to have resolved itself.
I'm assuming for the $100+ the real one better be reliable.
Every printer for the past 20 years has used USB B
USB 1.x type B definitely wasn't short lived, I've picked up new devices with a B connector in recent years.
The B connector you pretty much never see is the USB 2.0 one. Pretty much all devices I've seen use the wide version of USB Micro-B or, you know, USB C.
ACAB: All Connectors Are Beautiful
usb microphone, usb audio interface, midi keyboard, printer they all use it
Wait until you learn about USB 3 with connector type B.
Suuuubtle. Love it.
Is it supposed to resemble a cop pulling a gun?
Nah, It's USB type A, C, A, and B 😉
That's genius, im stealing this!
I think that “ACAB” is a bad thing, however I have to admit that this is clever
I think cops are a bad thing and I agree that this is clever.
