The problem with USB-a isn't that it's non reversible, it's that it's non-reversible _and_ rectangular, so it's not clear at a glance which way round it should go.

All they had to do was make the connector have a non-symmetrical shape so that it's immediately obvious which way round it goes when you pick it up - you could do it without even looking. Think of how much time we'd have collectively saved with this minor design change.

I disagree. When connecting an HDMI cable I sometimes have issues, especially if in a weird angle.

However I do concede is faster to connect an HDMI than a USB

[dylan604]

Yeah, I want the connector that can be attached by only moving the TV a few inches, just enough to get my hand to fit and feel around, not something I have to rearrange the furniture for and break out some headlight to see which direction the cable is oriented. With BNC cables, I could do it with my eyes closed.

[rainbowzootsuit]

I find that a USB-A fits reasonably by feel into an Ethernet port for extra points.

[macintux]

Conversely, I plugged my USB-C cable into a USB-A port by feel recently, and didn’t notice until much later that it wasn’t charging.

[fsckboy]

I did that today! right hand side of lenovo X230, then wondered why my mouse didn't work

[joshstrange]

Oh good, and here I thought I was the only one who had done that... more than once.

[FrankoDelMar]

Admittedly I did this today.

[kuschku]

Tbh, humanity should've just used SDI for everything.

[marcosdumay]

The problem with the HDMI connector (well, the problem on topic here) is that it's almost rectangular. Just a pair of small chamfers doesn't cut it.

Display port has a much more usable design, with a chamfer that is about twice the size as HDMI.

[somat]

Right, the only thing worse than USB was the PS2 port. What sort of madness drive someone to invent a round connector that is keyed.

Hyperbole aside, there are some very good reasons to go with round connectors, it can be very strong and you can put a big nut on them to have an extremely secure lock. however the PS2 connector is nether of these things, It would require a much more robust key to work well.

The worst connector I ever encountered was on a old ATI capture card, it was the same barrel as a ps2 connector but had about 15 pins. Everything had to be perfect for it to insert, a tiny scratch or a slightly bent pin, it was not going anywhere.

[antiterra]

The PS/2 connector was just a mini version of DIN connectors from the mid 1900s. They were sometimes used for printers and floppy drives in place of wider parallel connectors. In general, once you knew where ‘up’ was you could figure out the orientation in a way that is still more intuitive than USB. XLR cables are similar and still widely used, but have more external cues as to their orientation.

[akerr]

I would line up the barrel and then rotate while pushing in until it plugged in. I don’t remember bending any pins. The mark on the top helped until the tower form factor turned the motherboard sideways. Still do this for XLR and MIDI but they’re more robust.

The Apple desktop bus (ADB) that was used for keyboards and mice in Mac-land was also round. They improved it by using asymmetrical plugs, which marginally helped.

[jonny_eh]

For an example of an asymmetrical "rectangle", look at HDMI: https://en.wikipedia.org/wiki/HDMI#/media/File:HDMI_connecto...

[dweekly]

DisplayPort is even simpler; a notched shaved off of one of the corners.

[carstenhag]

Still very difficult to plug in, also often struggling with its orientation.

[kergonath]

FireWire was great for that. I loved that connector.

[Paianni]

The 6-pin connector was nice. But laptops and camcorders generally had the 4-pin connector (sans power)...not so nice.

[kergonath]

Indeed. The small one was very flimsy and annoying to use.

[eternityforest]

Wasn't it based on the GB link cable?

[kergonath]

I’ve seen that claim but AFAICT it comes from a single source, which was a presentation by someone involved in the FireWire connector design. So at this point it’s more of an urban legend, until we have some solid confirmation.

It does not really matter though, they are very similar in construction, and are very sturdy, and I really like them both :)

[extraduder_ire]

I've seen the same claim made. Apparently it was the sturdiness that led to it being copied. Good enough for kids beating on it and stepping on the ends, more than good enough for professional applications.

[Macha]

No, they both used the same physical form factor, but it seems to have just been a model from a OEM used by both nintendo and apple around that time, rather than one spec deliberately copying the connector from the other.

[stevage]

Even having a bump on the rubber moulding as part of the standard would have solved the problem.

[Smoosh]

Heck, just making the plastic insert white instead of black (now sometimes blue, occasionally orange) would have helped.

[noizejoy]

Frequently (by convention) the colors on the USB ports have meaning (including white actually indicating USB 1.0):

https://duckduckgo.com/?q=colors+on+usb+ports

[rzzzt]

The USB symbol goes on top, IIRC.

Edit: ninja'd by an enormous amount of people elsewhere in the thread, gah.

[qup]

This is not always true, and not all ports are horizontal anyway.

[edgedetector]

Isn't it part of the standard?

[Talanes]

In relation to the PCB, so if they're horizontally mounted onto the motherboard, you end up with vertical slots on the back of a standard tower.

[askvictor]

Yes.

Does everyone follow the standard? No. Including big names that prefer to have their logo facing up.

[Suppafly]

It doesn't help if you've trying to do it totally blind, but the 2 open square holes go on top, once I figured that out I've never had any issues plugging them in correctly. The only one I have issues with is my keyboard because the pcb in the plug is black and the it's a little hard to tell which side is the open holes and which side is the black pcb.

[denton-scratch]

> The USB symbol goes on top, IIRC.

For some values of "top"; that is, some device manufacturers install the socket upside-down.

[Moru]

Vertically aligned motherboards are hard to judge what "up" is. Usually up is where the expansion boards are plugged in. But not all computer users know how a computer looks inside.

[ngcc_hk]

Apple and many others need to be reverse always. There is no top.

[lttlrck]

Right, don't make a non-reversible connector appear reversible... I would have thought this is Connector 101.

It's so bad it takes me 3 attempts to plug in USB-A blind, at least 50% of the time.

[ilyt]

other part of connector 101 is "put the springy bit on the cable, not socket, so when it wears out you replace a cable, not connector"

Given how Mini-USB looked I'm gotta say nobody there had any clue about designing connectors...

[davidgay]

That only works when you can see the place you're connecting to, or have used it many times.

I've definitely cursed many times failing to plug in non-rectangular VGA, serial and parallel cables ;)

[edit: it is still better, but not a panacea]

[mcny]

Just curious if you have seen the special irregular USB A plug for the Lenovo Yoga 3 Pro. If so, what are your thoughts on it?

[fennecfoxy]

Tbf I think the most prevalent issue with USB was from people plugging them in where they cannot see the port properly, ie the back of a computer tower (most often) or back of TV/console etc.

Not really sure that that's USB's fault so much as a lack of front USB ports. I think in those cases the consumer can chose to get some sort of hub that's easier to access/can be pulled out from behind their setup.

Now that C exists though, idk if we really need to go much further. Connector much smaller than it is now will become fragile.

I've always thought they could add a single fiber core to USB cables for some "ultra high speed" standard, since USB4 is predicted to top out at 80GBps, but we could get 50Tbps or so over a single fiber if we really needed to.

But after owning several fiber cables, for networking and HDMI fiber based cables...yeah they're far, far too weak to replace copper. Just look at 'em wrong and they snap/break.

Plus tbf if we get 80gbps from usb4...the problem then becomes that we don't reaaaally have a use case for that speed. Maybe network adaptors, but beyond that...I mean a modern SSD will saturate that with a sequential read I suppose, but still.

[themerone]

They did that from the beginning with USB-B, but they never standardized an orientation.

[kelnos]

I guess it would be easier with the larger size of the USB-A connector, but I still struggle to plug in micro-USB cables sometimes, as it's still difficult to figure out its orientation at a glance.
