TL;DR: its cheaper that way,
And i value that decision
I can bet you it’s incompetence. They failed upwards. Sure, protocol is great and universal, but connector is atrocious and it has nothing to do with cost. Few points in favor of this hypothesis:
- Plastic inside of the connector was initially black. Why chose hard to see color? Go with something easier to see;
- Connector is perfectly rectangular and only distinguishing feature they made hard to see. Don’t make ti symmetrical if it’s not reversible, basic design principle;
- Connector is perfectly rectangular making it difficult to insert. There’s a reason why most connectors have rounded corners, they are self-correcting, even TypeC does this;
- They made various different connector types but pushed for the only one with these issues. No one ever had doubts how type B or mini B or micro B go in.
Initially, the plastic inside the connector was white. They started to use black to denote USB2.0 devices, and USB2.0 rapidly became the standard. They at least tried to do something similar with blue plastic with USB3.0.
It’s basically the only example I can think of where the plug and socket are rotationally symmetrical without also being reversible. That’s the kind of thing where I ask “did you test this before you shipped it?” Thirty years later we’re still plagued by the damn thing.
Right you are. Completely forgot about that. That said, I don’t think USB1 was a standard for too long. If I remember correctly it went to 2.0 pretty fast.
Also a male USB 2 plug fits perfectly into a RJ45 slot :-/ In my days of tech support, I’ve seen multiple people plugging their USB printer cable into the network slot of their computer and it’s a perfect fit so they were always convinced they didn’t do anything wrong… That’s clearly a design flaw while all other connectors have distinct sizes.
Never heard of people plugging USB into LAN, but now that you mention it they are the same size. Luckily all the contacts are shielded.
Way back before USB, joysticks had a DIN-25 connector that was identical to the MIDI network connector.
I blindly plugged my brand new MS Force Feedback joystick into the MIDI network port behind my miditower (yes I’m that old) and watched the magic smoke rise out of the joystick. That was not a good day to learn about plugs. The network carries 50 volts or something. Stick wasn’t happy.

My girlfriend works in IT at a school so I asked if she’s encountered this too. She said “all the time, they’re right next to each other” she also added that a lot of people put their thin charging cables into the headphone jack breaking their laptops. And that for some of them they “fit better” in that jack than the one it’s meant to go in.
No one ever had doubts how type B or mini B or micro B go in.
I agree with most of your post, but micro B is a step too far. That fucking plug was always inserted with the following procedure:
- Try to plug it in.
- Flip the side and try to plug it in again.
- Flip it again because you had the right damn side the first time.
Always, always, always.
Hindsight is 20/20. You’re raising every issue with the original USB plug, then proceed to highlight how they addressed these issues going forward.
You’re describing inexperience and calling it incompetence.
AFAIK the real predecessor to USB was Serial cables and those were an absolute shit show. USB set out to create a more usable interface with a lower profile and cheaper cost. In many ways the minor flaws in USB becoming common gripes is USB becoming a victim of its own success. I don’t think they originally set out to become a power charging standard so the frequency at which devices were plugged in increased over time .
I don’t even know that I would call it inexperience. I just think a major part of the first pass was selling the idea of USB. You can design a perfect cable, plug, and protocol, it doesn’t mean anyone will use it. Most investors don’t know much about the technical details of a product. They do, however, understand the price. If you’re trying to make a difference in the world, you don’t always get to do it with style and quality.

How lucky you were to never have a device that had one of these upside-down.
USB-A walked so USB-C could fly.
You need that for power regulation. One of the reasons that you can use a USB-C lead with anything is because all of the devices that require different power will just tell the cable that and the chip inside the cable deals with it. Otherwise there would have to be different cables for different voltage requirements.
A chip can literally just contain basic logic gates. Your aversion to them is based on pure Qanon fiction
EXPLAIN!
The reply is pretty self-explanatory too. The cable exists in a 4-dimensional space.
It doesn’t necessarily need to be 4-dimensional https://en.m.wikipedia.org/wiki/Spinor
“In geometry and physics, spinors /spɪnər/ are elements of a complex number-based vector space that can be associated with Euclidean space.[b] A spinor transforms linearly when the Euclidean space is subjected to a slight (infinitesimal) rotation,[c] but unlike geometric vectors and tensors, a spinor transforms to its negative when the space rotates through 360° (see picture). It takes a rotation of 720° for a spinor to go back to its original state. This property characterizes spinors: spinors can be viewed as the “square roots” of vectors (although this is inaccurate and may be misleading; they are better viewed as “square roots” of sections of vector bundles – in the case of the exterior algebra bundle of the cotangent bundle, they thus become “square roots” of differential forms).”
Seems pretty self-explanatory to me! /s
Somewhat understandable, but they could’ve also done something like HDMI and DisplayPort and gone with a shape that could only plug in one way. It might not have been “as cheap as possible” but probably not as much added expense as the extra wiring and stuff. (maybe, idk shit about manufacturing)
The problem there is at least as much from how hard it is to twist the cables as it is from the connector shape. The asymmetric connector is still better than nothing.
I can think of some examples of asymmetric connectors that work great: mini USB; North American 3-prong power plugs; old school PC video, serial, and game ports; original NES controller connections, etc.
I really wish hdmi was symmetrical. (Peer behind tv, “which way goes up?” Tries to plug it in, “fml it was the other way” flips it drops it)
Unfortunately HDMI already uses pins on both sides of the connector, so you would have to shrink them to half their size first, then double them.
Not all asymmetric port designs are good. SCART was capable – HDMI of the 1990s-2000s – but you cannot really feel where one ends and another begins with 2-3 of them in the rear of almost every TV and VCR sold in Europe back then. They carried flawless RGB video, two-way composite A/V, remote control signals etc. However, they were bulky (why 21 individually shielded wires instead of twisted pairs?), expensive and got loose easily. This was before digital technology that enabled error correction and multiplexing.
About a decade ago or so, I found myself in a reddit argument with someone that claimed they had never attempted to plug a USB in unsuccessfully. They said that every single time they’ve plugged in, it was the correct way. Some people are insane.
Honestly, with high quality USB A plugs you could feel the logo on the side that was “up”, and if you knew which side your motherboard or front panel considered “up”, it’d be easy to always plug devices in correctly.
Just that the vast majority of manufacturers stopped caring relatively early on, which meant you couldn’t rely on it anymore.
The logo isn’t that reliable but it’s usually slim side up. Not sure about sideways ports though.
They’re supposed to label the USBs so that you can tell which side is the top side and which side is the bottom side.
The problem is that, A they often don’t label them and, B I can’t remember which way round it’s supposed to go anyway, so it wouldn’t help.
- Attempt to plug in the USB A device
- If you succeed. End procedure
- Otherwise, destroy the reality you currently reside in. All remaining universes are the ones where you plugged in the device on the first try.
That wasn’t so hard, was it?
Perhaps a controversial opinion here, but the usefulness of reversibility is vastly overrated. It’s not a game changer, just a tiny first-world luxury that’s nice to have, but it does it by introducing a bunch of unnecessary complexity that I’d rather avoid. Not worth the trade off IMO. I can count on one hand the number of minutes USB-C has saved me by being reversible and I honestly don’t care
I’m happier with how long usb c last before they start getting finicky than I am the reversiblity.
In theory, USB-C should be better, but in practice, the quality control is all over the place.
All of my micro USB cables and ports have lasted just fine. I used one daily with my phone for 10+ years with no issues, and I’ve only had maybe two cables ever actually fail. Meanwhile, I’ve already had at least 5 USB-C cables or dongles that have fully failed, and plus the primary USB-C charging port on a laptop just completely die. I wish it was better, but it just isn’t.
Also if USB-C was just replacing just micro USB I’d be ok with that. But the problem is they’re also replacing USB-A, and Type C is not nearly as durable as Type A since it’s so small, it’s just physically impossible. I wish they made a larger version of the Type C port. Same shape, same pins, just bigger in every dimension. As large as Type A, for durability.
I’m not a big fan of Apple, but the lightning connector is just better, physically. It’s way more durable in practice since it’s just a solid piece. I wish USB-C was designed that way instead of what we actually got.
The issue is that USBC was the first standard to really take the mechanical design process seriously in a consumer context. In doing so, it was made both way more ergonomic and way more durable. I’d argue that without the focus on some of these “small but marketable” consumer-oriented bits, we would not have gotten the great overall connector design we did.

I am just laughing here because I spent the day dealing with ancient serial tech pigtails and DB9s. You people have no idea the pain of losing multiple days of your life trying to get RS-232 to work. Especially when stuff doesn’t follow the standards it is supposed to follow.
Well if you only plugged one USB in your life you have a 50% chance of never having plugged it in wrong.
Well, I rarely fail because I look inside the connector and see where the plastic is and then plug it properly. I tend to fail when I cannot see inside the connector because it’s in a weird spot.
I guess the redditor was either bragging about always looking inside or was a kid
I mean if you tend to plug things in at the same computer a lot it’s pretty easy to always plug things in right the first time, even when not looking because you just kinda know what way it’s meant to be. And laptops usually have all theirs pointing the same way so you know one you know them all. If something has text on it, it’s usually oriented in such a way that when plugged in you can read it. Or they have a little face and you know which way the face is meant to be facing
I have a similar “power” and while I’m not flawless, it’s only really new or unfamiliar devices/computers that trip me up. Or plugs that don’t actually have any identifying features and/or unusual ones
That person is either a flat out liar, or they are incredibly anal and waste a lot of time looking at the connector and input every single time they connect a cable.
I don’t really have a problem looking at the connector before plugging it in. I thought this was an overblown meme.
I wouldn’t say it’s never happened to me but 99% of the time it works. I just look at the idents, face it right way up, and shove it in. Unless I’m drunk or it’s dark, I’ve never been able to relate.
