I honestly never had issues with most of the usb devices. The side with two holes is the upper side.
The problem is that not every manufacturer orients their ports correctly
Making USB reversible to begin with would have necessitated twice as many wires and twice as many circuits, and would have doubled the cost. Bhatt says his team was aware at the time of the frustration that a rectangular design could have, versus a round connector. But in an effort to keep it as cheap as possible, the decision was made to go with a design that, in theory, would give users a 50/50 chance of plugging it in correctly (you can up the odds by looking at the inside first, or identifying the logo).
would give users a 50/50 chance of plugging it in correctly
Sometimes it’s more 33% or even 10%.
I was there when we had lots of “round” connectors like Din connectors but also lots of proprietary ones.
That was way worse, trying for the eleventh time to put it in correctly without looking as it’s under/on the backside in a jungle of other cables, and not damaging any of the fragile 7 pins… gargl.
Yeah. I will always hate USB A and went a bit overboard on switching as much as possible to USB C the moment it was even kind of viable.
But… if USB A is the “This marvel movie is the worst movie ever made” of complaining, people would lose their god damned minds if they ever had to deal with ps/2 (a direct to dvd movie starring mel gibson) or some of the serial style plugs that were rectangular instead of trapezoidal and had asymmetrical pins (a recording of an improv group)

More “retro hardware” enthusiasts.
From a keyboard perspective? Cherry Blues are too mainstream. Everyone now needs one of those god awful ibm keyboards from the 70s (?). Because how can you type a screenplay if people in the Starbucks three towns over can’t hear you?
But that has mostly manifested as switch modding and new designs. Because ergonomics and layout matter a lot too. I mean. how can you get anything done if you aren’t rocking at least TKL?
But there are people who have access to older hardware. Either because they had it in the basement for 30 years or because they got gouged on ebay. But the USB->PS/2 adapters have been on the market basically forever. Not in huge quantities but they are also dirt cheap to make so more or less any store that sells “electronics” has a few collecting dust.
But it also more or less has the same problem facing “retro” consoles. Old “indestructible” NESes are… mostly dead. It is increasingly hard to find working models and a lot of those end up getting torn apart for parts. It is why we are seeing a growing acceptance of emulator runs in the speedrun community and a push to “vet” the FPGA solutions.
And same with the classic typewriter style keyboards. A lot of them just have broken switches or damaged electronics from decades of cigarette smoke and so forth and are parted out or completely unsalvageable.
USB->PS/2 adapters
That caused a flashback, as I haven’t seen those in years (but I know I have a few still somewhere lol). It also made me think…I can not recall ever having to do the “1-2-3” tries when hooking a USB mouse or keyboard into those before I plugged it all into the back of the PC. Which makes me lean towards blaming the socket installation and lack of reference for a lot of the woes, not the cord or flashdrive (which you can see).
The trick with DIN connectors was to try to insert them gently while rotating them. Once you got the notch lined up they would very clearly drop into the socket at which point you could apply more pressure to fully seat them. It was only a problem if you were jamming them in full force while rotating because you could exert enough pressure to force it into the socket even with the key notch misaligned crushing the pins. I never once had a problem inserting a DIN connector, something I absolutely can’t say about USB-A.
Wow I’d forgotten about the old keyboard and mouse ports, they were such a faff to plug in without looking.
I have my doubts. I think that a jack-like (circular) connector wouldn’t require twice as many wires and circuits. Actually absolutely the same amount. The connector itself would require more metal to make.
And the chance of correctly plugging that in would be like 99/100 (1/100 for breaking it).
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.
- 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?
I feel like that’s a way to rapidly run out of spare universes
If it’s on a laptop I could see it. The empty half almost always needs to be on top on the male side because the female end is almost always plastic on top.
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.
Most things I have are labelled properly, and I’m only hedging my bets by saying most because I can’t think of anything I own that isn’t labelled properly
Well if you only plugged one USB in your life you have a 50% chance of never having plugged it in wrong.
USBs have three sides so it’s 33%
I believe it’s actually 0% bc the 3rd correct side only reveals itself after you fuck it up twice
If you can see through the two rectangular cutouts on the plug, it’s the right way around. Unfortunately, this doesn’t help if the plug is turned 90°, and also some computers have it upside down (looking at you, GPD).
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.
Overall not a huge deal to get it wrong occasionally, but to lie that you’ve never attempted to plug a USB in the wrong way up is 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.
Only usually
I say usually but it’s basically the rule. Of all my things only the QNAP NAS has a slim side down port, and maybe that’s some other convention I’m not aware of since it’s for the copy-data port. That’s among a random pile consisting of a Cisco networking equipment, Intel NUC, old macbook, new microsoft and HP laptops, a hdmi/usb switch, ps4, and a raspberry pi
Ooo so much tech, much IT /s
I’m an IT worker so ya I have a bunch of junk and I’ve seen a lot of ports
Which is why that person is/was a massive liar.
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 do not have a problem with looking at the connector when I can see it. But often enough I am fumbling a cable into some connector behind a PC, docking station or at night when the light is out.
Maybe he did it only once and worked out of luck.
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

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
Engineering centric worldview versus user centric worldview.
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.
That’s not going to get you Thunderbolt, mate
USB C was designed so that the spring contacts that wear out/get damaged are in the relatively cheap cable, and the solid, more durable tang that the contacts slide on is in the expensive device.
Now let’s have a look at Apple’s design for their lightning connector… hmm I wonder why they designed it like that?
I’ve never had a good experience with micro-USB, mini USB was meh, but for whatever reason the stuff using micro was always bad.
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’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.
If I recall correctly, Lightning connectors are designed in a way that makes the port more likely to wear out. USB-C is designed in a way that makes the cable more likely to wear out. I would rather replace my $5 charging cable than replace my $150 (or more!) phone.
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.
Yes, you’re right: that was controversial.
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 wonder how that redditor is doing now? Still batting 1.000 with USB A adapters?
EXPLAIN!
USB-A is a spin-half connector type
It doesn’t necessarily need to be 4-dimensional https://en.m.wikipedia.org/wiki/Spinor
deleted by creator
That entry needs a ELI.
“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

The picture explains itself. The cable exists in a 4-dimensional space.
The reply is pretty self-explanatory too. The cable exists in a 4-dimensional space.
You guys joke about this, but he managed to create a connector with three sides: up, down, and “oh yeah the first side was the correct one”
I learned a long time ago that it takes three licks to get to the Tootsie Roll center of a Tootsie Pop, because commercial breaks during Saturday morning cartoons told me so. Sometime later, I also learned that “three” is usually the magic number for correctly plugging in a USB Type-A device.
……what the fuck?
Edit: Guys, I get the reference to Tootsie Pop ads and that USB-A connectors are often stubborn to connect. The “wtf-ness” comes from the writer making such an oddball reference just to arrive at the number three
Still not sure what that has to do with tootsie roll pops, other than the number 3? Explaining why someone said something doesn’t automatically make it not weird
No, I know, we all know the ad, we are just trying to figure out what that has to do with USB’s other than a use of the number “3.” It’s a really weird part of the article that elicits a “wtf” whether you get the reference or not. Getting the reference doesn’t make it not weird.
Oh yeah, no, I agree. I just wasn’t entirely sure, if they thought it was even weirder than it still is, because they did not know the joke about the USB sticks. Just trying to help via dumb memes. 🙃
I can respect that
If you’re still confused, it’s an apparently universal experience to try to plug in a USB, feel resistance, flip it, feel much more resistance, and then realize you were correct the first time. Hence, three is the magic number.

Yeah no I get the reference
But in practical use, people found out that even a 50/50 chance of plugging the connector in the right way is annoying enough to warrant the additional complexity of reversability, hence the development of USB Type C.
The USB-C design turned out to be much more durable and versatile (signal and power wise) in addition to reversability compared to the previous USB designs, and it is developed specifically to address the problems people found with USB-A/B/MicroUSB.
Sometimes problems only reveal themselves through real life usage, and iterative improvement through a scientific trial and error process to address these problem is how you get development progress.
For USB-A, it’s usually not even 50/50. It’s the witchcraft superposition when the first two tries don’t work.
First try doesn’t go in: oh I guess I have to flip it. Second try doesn’t go in, fiddle it a bunch still doesn’t go in. Fuck I had it the first time. Third try goes in immediately
It always works the third time, 60 percent of the time.
Yeah, people don’t take into account quantum positioning, pass-through phenomenon, or the fact that I can’t “see” when I plug it in wrong and that makes me think maybe my fingers are dumb and I missed the hole and not that I need to reverse it and try again.
I wish it was 50/50. A lot of the time it wouldn’t plug in so I flipped it. Still didn’t work so I flipped it back to the original orientation and it magically plugs in.
USB & me: third times the charm!
Can you imagine if it was a triangle with only one correct way to plug it in?
Apologies to the shit alternative universe I just created
USB-C has more connectors for data and power than A/B so it’s not a surprise that it’s more capable.
What’s really changed is demand. No one really expected USB to be used to power everything, it was only ever really expected to be used on computers and maybe digital cameras, smartphones used to arrange matters for themselves. It was only when they two began to adopt USB aas well that calls for smaller ports and higher capacity cables started to arise.
No one really expected USB to be used to power everything
Yeah, it’s not like the U stands for Universal or something.
As long as it’s a serial bus
Yeah, Universal Spower Bus. Sounds right. I was reading the “power” part emphasized in the comment you replied to. Prior to mass adoption by phone mfrs, USB wasn’t powering all that much. You’d usually have 5v wall wart and cable ending in a barrel connector. Hate those things.
The barrel connector was reversible, and I don’t think I ever had one fail.
They did always use way too much space with their AC adapter things and for whatever reason nargles liked to steal them.
I chuckled more than I would like to admit about that spelled out USB name, dunno, it’s funny
The Universal Spower Bus
sounds like an awesome transit vehicle!
Let’s take a ride!
Edit: Spower is a contraction of Space and Power. Yes, you heard me right. It’s running on space power!
And here it is:
I’m not really sure what that means. The original A/B specification did not allow for much variable voltage. It’s only universal in name, not in nature. There was absolutely no way to deal with high voltage devices, the cables were not adaptive.
USB 4.0 specification allows for powering things like electrical drills. No way the original USB A/B specification can handle that.
You are right to an extent but the context of its original universality is in the rest of the name. Universal serial bus. The idea was a universal port for dealing with data and connections not neccesarily power.
And yet it still can’t retingulate droopglers. Pathetic.
We are way past it being just a power thing though. USB-C is effectively the standard wired general purpose data bus these days. It’s slowly cannibalizing HDMI and DP as well (via thunderbolt), in addition to power cords.
Is so dumb that HDMI or DisplayPort over USB-C is called “alt mode”
The USB Consortium are the only group worse at naming things than Microsoft.
The worst parr is it used to be good naming scheme. After 3. They went back ended the meaning of 3.0 and 3.1 and made it bad
Can someone explain to me why I keep reading about people having problems plugging in USB A connectors upside down? I feel like I’m taking crazy pills. Per the spec, the holes always go up. They indicate the correct way to plug in the port. Not only that, but the printed logo on the connector also always goes up.
The only time this is SLIGHTLY confusing is if you have a desktop tower where the motherboard is essentially mounted sideways, but for that case it just takes an extra second to think which way is “up” from the perspective of the motherboard.
And before anyone says “who reads the spec?”, it feels like I subconsciously knew this for something like a decade before I even knew what a spec was.
I’ve seen enough devices with the usb ports mounted upside down, for whatever strange reason. Also sometimes you want to plug something in without looking, this is much easier with USB-C
That’s wild, I’ve never seen an upside down port.
I agree reversibility is better and am happy usb c will finally kill this meme.
Sometimes you’re working on an IoT device in a tight space, which makes rotating/seeing everything much harder.
Especially if you drop the cable it falls into a crevice somewhere.
You probably won’t have trouble plugging it in the first time, but gods forbid you unplug/replug it then the cable rotates 540 degrees and you have no idea how it was plugged in before
Yeah that’s fair. But I feel like I’ve seen these “USB superposition” memes since before IoT was even a thing.
How many other plugs are reversible? HDMI and DisplayPort aren’t. Older stuff like scsi, gameports, parallel and serial ports and the like weren’t, and could even destroy your hardware if plugged into the wrong thing. Firewire and GameboyLink weren’t. Barrel plugs are insertable every way you want, but only have two contacts. And 3.5mm jacks slide over all the pins, which might not be great if you plan on carrying power.
Lightning and USB Type-C are reversible, but that’s the only one I can think of. And the inoffiziell rarely seen reversible USB Type-A (when were those first released?).
Biggest problem with USB Type-A is that it isn’t keyed in an obvious way, so both directions of insertions look and feel plausible until the thing doesn’t wanna fit.
PS: Another thing “wrong” with USB is that Type-B isn’t a female Type-A, but a completely different thing, meaning a USB cable can’t be used as extension cord and you need a different cord for that. As I understand it, this was done deliberately to avoid issues with cable length and voltagedrop and signal degradation (which you run into anyway when using USB extension cords). There is also the hermaphroditic connector, which keeps the sides the same, while still allows extension cord use. Don’t know if anybody ever implemented that.
I must be dumb cause I still need 3 tries to plug in a HDMI/DP port.
USB B takes 6 tries: first three times in a RJ45 port, then 3 more after realizing I’ve been messing with the wrong port all this time.
IBM token link connectors were hermaphroditic
Didn’t have to be reversible. Just obvious. Both HDMI and DisplayPort go in only one way. It takes fiddling but there’s no doubt. With USB it’s always you fiddle, doesn’t fit, then maybe it’s the other way around, doesn’t fit, oooh it was the original, doesn’t fit… ffs. And they even made the plastic black.
I used to work in a call centre and a lot of headsets use that connected design.
Neat, never heard of that, guess it’s not seeing much use outside the professional setting. It’s called Plantronics QD.
So, thanks for the PTSD I don’t think I’ve seen those ports in over a decade. Pluging in your headset into those ports was like submitting to torture.
But yeah that’s them.
It’s really interesting that they never became standardised outside of the call centre industry because really they would have been great in consumer electronics and I’m not sure why they never became popular.
Here is an alternative Piped link(s):
Piped is a privacy-respecting open-source alternative frontend to YouTube.

I think the big thing with Firewire and DisplayPort, though, is that the port isn’t a rectangle. It’s flush on one size and angled on the other so that you know which way it plugs in no matter what. It being non-reversible wasn’t an issue because of that. USB, on the other hand, has the same shape whether it’s right-side-up or upside-down.
Yeah, I don’t think the complaints stem from the connector not being reversible but what you described in the last paragraph.
Yep. It’s not that it isn’t reversible, it’s that it’s non-reversible contacts inside a symmetrical connector.
Which boils down to: people want to be able to plug something in without thorough inspection.
An easy, cheap solution they could have popularized from the start would be to print something like an arrow on both the port and plug to line up visually.
Apparently manufacturers are only supposed to put the logo on the top. But since a lot of companies didn’t print the logo, or only embossed the logo so you could barely see it, or put the ports on the parent device sideways, this was never much help.
Combine that with the fact that they never actually told anyone this, and it was basically useless.
Most people weren’t adding and removing peripherals (and potentially multiple things using the same kind of connector) from their computers multiple times a day when many of your examples were in common consumer usage.
Now we plug and unplug peripherals all the time, and for a great many people those multiple plug/unplug cycles are all using USB, and have been long enough to have plenty of frustration about this.
I don’t think Type-A or its creator should burn in the depths of hell, but it’s a legitimate complaint for a usage case that most people didn’t experience prior to loosely about the time that USB started to rise in popularity, or so my recollection of the chain of events tells me.
Depends, back in the home computer days swapping around joysticks and mouse (and less often lightpens and paddles) was a pretty common occurrence. And over in the console world we had multiple gamepads, multitabs, GameBoy Link cables and the like that also saw a ton of plug-in action.
PC was somewhat special, since joysticks, keyboard, mouse and printers all used different ports, often only accessible on the hard to reach backside of the PC case and sometimes even screwed in. Hotplugging was also not officially supported. Those are however all the issues that USB was specifically designed to fix, so more plug-in action was to be expected.
That said, it is quite true that reversibility really wasn’t a concern back than at all. None of the other ports had it, and USB was a huge improvement over previous PC port designs.
People who find that “frustrating” have led too sheltered a life.
*with the exception of some who have specific disabilities
It’s not a big deal but add up the billions of times people needed to plug a USB 3 times instead of one and that’s a lot of wasted hours.
It can be frustrating without being the most frustrating thing. Mild annoyance repeated many times becomes pretty annoying.
While I agree this is no big deal, but I also don’t think anyone is saying this is the worst problem ever. Another person starving doesn’t make me any less hungry. I don’t think it’s super helpful to say what is and isn’t annoyance/problem for people.
What a pathetic excuse. You know what’s at the other end of a USB-A cable? A USB-B connector that didn’t have the symmetry problem. Also, Firewire existed around the same time (in fact, slightly earlier) and didn’t have the symmetry problem.
FireWire was an amazing interface, and nothing has quite come as close. The ability for devices on a FireWire daisy chain to talk to each other without the computer being involved made it excellent for storage
I get why it’s not reversible. But why the hell is it not keyed so that is obvious which orientation is correct? A small, cheap, notch would have worked wonders.
It kinda is keyed. Seam goes down.
That’s true - I mean to make the keying more obvious. As it stands it’s all internal and difficult to see.
But does it go right or left, back or forward in other rotations?
Seam goes down, as oriented to the motherboard. If the slots are vertical, usually to the right? If you have a rare, weird machine, just remember which way it goes. FFS, there are 2 choices.
EDIT: Having said all that, not sure I’ve seen a machine that orients the seam to the left. ?
Until they created upside down Jacks
Some USB sticks have the logo on one side, some have it on the other…
I honestly think that FireWire 400 had a better physical design for the connector. It was keyed more dramatically than some of the other connectors people are citing as being both keyed and easy to orient incorrectly. I personally never had issues plugging in FireWire 400 blind.
I loved FireWire, if we had adopted it instead of USB we’d all be driving flying AI cars by now.
The stuff it could do was really cool, you could network computers, daisy chain it, it could transfer data in real time systems (like digital recording or audio setups), and it was actually designed for power delivery, plus it was much much faster than USB (at the time).
Almost all connectors in use on computers at the time USB was introduced were already keyed, and a fat lot of good it did us. Ask anyone who tried fumbling around behind a three ton CRT monitor or computer case – even with the keyed connectors, feeling for which side was up, getting anything plugged in without eyes on it was already nigh on impossible.
What the USB A connector did do which was new at the time was introduce a connector that did not have any protruding pins on either the male or female end, and thus theoretically at least could not be damaged by fucking up the insertion. Unlike any of the then-common D-Sub connectors (VGA, serial, parallel) or DIN (PS/2 mouse and keyboard, Apple serial, S-Video, etc.). USB didn’t even have the little clip to breal off like an RJ-45 Ethernet or RJ-11 phone line connector.

This is not true.
Some 80s computers had cassette player interfaces that practically looked like big USB connectors.

My first computer. Bless you.
okay but the clip on rj connectors is a locking mechanism which usb just lacks… break off the clip and they’re relatively equvelent no?
No. USB uses friction retention, whereas a clip-retention cable sans clip has real risk of simply falling out.
What the USB A connector did do which was new at the time
Gameboy Link cable did that earlier and subsequently inspired the Firewire connector (and also happens to look a little like Type-C with the contacts in the middle).
Keying does no good, have you tried fumbling with a serial port connection before? Same difference, and it’s keyed too.
What’d have helped is clear markings and plug heads, like how some DIN connectors are done: The orientation simply cannot be missed.
Yeah, it’s orientation I mean more than keying. USB-B was much easier to plug in than A. Orientation is very clear.
The problem for me was never the plug, but the socket. It was obvious to me which side had the connectors, it’s the sockets on devices that would be random rotations most of the time. I never really understood the extreme hatred, while it wasn’t perfect, it worked well. I inserted successfully a lot more times than not, USB-A served us well in all honesty, but glad we have moved on to reversible.
I actually have some USB-A to USB-C cables from DeWalt with reversible USB-A connectors. Certainly no reason other companies couldn’t have built them that way.
Yeah, I bought some JBL sound equipment and those USB-A side cables are reversable too. Just a flap with the connectors on both sides.
To save a penny on each connector. The USB group is ran by hardware manufacturers. They do not have innovation as a core value.
the problem is the plug is rectangular (has exterior rotational symmetry) AND not reversible - if the plugs were L shaped it would be clear by both feel and brief glance which rotation was correct
Reminds me of how we used to change the order of the wires in PC to PC connections on early RJ45 cables. What a fucking pain in the ass that was for colorblind like myself.
Ah yes: “crossover or straight through?”
I had always wondered what that was like for colour blind people.
Let’s just say that I didn’t do too well when I wanted to become a helicopter engineer. Color coding is one of those things that are both inevitable and impossible.

But why is USB C directional? One phone I have won’t charge if the cord is in one orientation but fast charges in the other orientation.
Symmetric is the default but not required by the standard, so directionality is permitted if irregular.
Clean it. fixed
It isn’t. Either your cable is bad, or the port on your phone is bad/broken.
Technically cables are part double sided (USB3 wires, grounding) and part single sided (power, USB2), while ports should be double sided.
You just got a Zoolander cable, that’s it.
