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.
EDIT: Lots of people pointing me to printers and music gear with those ports! I dabble in music and my little korg nanoKEY2 uses mini USB. And I've not bought a new printer in over a decade (laser printer toner lasts forever). I think I unintentionally invoked Cunningham's Law here
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.
Yeah, C had two major innovations: it was symmetrically functional, and it was symmetrically functional. Everybody knows about how A was kinda a pain because you'd try to plug it in upside down a lot, but A also was unidirectional. You never see male A to male A cables despite A being so common, meanwhile C to C is the default C cable, even things that would have used an integrated cord often just slap a port on instead
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.
Wild, TIL.
So short lived you can still find it on brand new printers
In case anyone thinks you're being figurative, LITERALLY brand new printers. The Brother laser I bought last week is USB-B, as I expected it would be : )
This replaced the HP laser I bought in 2004 which was, of course, also USB-B.
Why change? It does the job. The cable doesn't need to pass audio or video, doesn't need to pass fast charge power, and sure as hell doesn't need 80Gbps data transfer speeds... the bottleneck will always be the print function itself. Usb-c would be overkill. And Usb-b is made to be secured to prevent accidental disconnection for devices that typically dont move like printers and scanners, unlike Usb-c which is made for repeated insertions and easy release for devices like smart phones. Only reason the connector might change in the future is if they either start adding stupid features to printers or if it simply becomes cheaper to support newer standards.
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
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.
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.
Are you thinking of the USB 3.0 versions of Type B? 1.0 and 2.0 should be pretty much indistinguishable.
USB B is still standard with audio hardware for some reason.
Because it's not short lived, it has a niche use. Basically its meant for receptor devices, whereas A is for host devices
Wait until you learn about USB 3 with connector type B.
And of course USB 3 micro B, the mangled step child.
usb microphone, usb audio interface, midi keyboard, printer they all use it
As others have pointed out, B is still well in use today. But it seems nobody mentioned why: it's because an A to A cable would be nonstandard and since there was no c yet, it's the a to b cables. C to c is okay and there are funky A to A things which shouldn't exist.
Honestly, it’s oddly satisfying how universal those symbols are. You don’t need words—everyone just gets it.
I think the people getting this are in a strong minority. Most people don't know that the archetypical USB port is called USB-A, and most people don't even interact with USB-B at all
Printers use B...and i don't mean just paper. Most 3D printers, crafting machines (cricut etc) and any form of arduino noodling will use B.
"How did you hook up your printer"
"Idk, the printer cable that was in the box"
"How did you hook up your 3D printer"
"I don't own a 3D printer"
that will be at least 95% of your interactions in that regard
"How did you hook up your printer?"
"I called my nephew who does something with IT"
That took me a hot second, but I love that!
The average person I know thinks of USB-B as "that squarish one." The existence of the differently shaped USB-B 3.0 doesn't help with this. Micro USB 3.0 also really throws people for a loop.
I think I've used maybe 3 devices in my whole life that use micro USB 3.0.
It was common for like five years on external hard drives.
And stupid is, even while you are able to connect 2.0, many disk won’t work properly with it (shows up in PC but file transfer just doesn’t work)
Yeah that was one or two of the three devices
Wow and its an acab reference?? Sold
Why doesn't it at least have USB-A 3.0? One of those ports needs to be blue.
Is that the "thin blue line" I keep hearing about?
