I’ve literally never seen any of these except the top symbol.
Some basic info about USB

I’ve never seen any of the SS 10gig or USB PD icons, but I’ve seen the rest. I’ve got Thunderbolt icons on at least 2 icons and SS USB 3.1 icons on many normal USB A ports.
MonkderVierte@lemmy.ml 2 months ago
Well, except all the legacy symbols on devices older than current gen.
Qutorial@lemmy.world 2 months ago
All they had to do was require stamped icons on the ends of the plugs in the spec, and instead we have this clusterfuck 🤦
Overshoot2648@lemm.ee 2 months ago
I legit have never seen the battery used at all. They often use a plug, a lightning bolt confusingly, or don’t even label it at all.

Why use more words when less is easier.
havocpants@lemm.ee 2 months ago
Fewer. Sorry, pet peeve of mine. If you can count the thing, it’s fewer, not less.

Honestly, I didn’t really have an issue with USB type A ports. They worked fine, and it was only a minor inconvenience to orient them the right way. I cared far more about capabilities of the port (speed, power delivery, etc) than I did about the actual port.
That said, micro-USB sucks in every way. The awkward “is this the right way?” thing is way worse than with USB-A, it’s not meaningfully smaller than mini-USB, the port is incredibly hard to clean (and it always gets dirty), and the connector seems to break all the time. I would’ve been totally fine with moving everything to mini-USB instead. The connector was less flimsy without being that much bigger, and it had room for more wires.
I do like USB-C though, I’m just not sure the added complexity is worth it.

I believe that the reason that the smaller USB variants showed up was because some devices were just too small to physically accommodate a USB-A plug. Think MP3 players and later – very importantly – smartphones.
For the vast majority of consumer electronics, USB-A is fine. But for things that are as thin as possible, usually to fit into a pocket, it starts to bump up against limits.

Mini-USB put the tensioners – the bit that wears out over time, is the bottleneck on the lifetime of the thing – on the (expensive) device rather than the (cheap) cable.
Like, I think that there was a legitimate reason to fix that one way or another.

aeronmelon@lemmy.world 2 months ago
Typically, the side of the plug with the USB logo is “up”. There are exceptions.
Also typically, if a USB port is vertical, up is to the left. Again, there are exceptions.
galanthus@lemmy.world 2 months ago
The SS ports must be faster because of german efficiency.
PMmeYourPenis@lemmy.world 2 months ago
I’ve never seen the one enclosed in a battery, but I’ve seen the rest.
AnUnusualRelic@lemmy.world 2 months ago
Those will legally do pretty much anything depending on what cable you use anyway. (and what cable you end up using is pretty much a surprise until you’ve tested it.)
All thanks to USB making our lives more simple. (yay)
Ok, I suppose it is more simple in quite a few ways.

So many different standards my god.

Me. Sigh.
serenissi@lemmy.world 2 months ago
The text. And probably images too (but the only mistake being the wrong port depiction (all c) says more human).
Eiri@lemmy.ca 2 months ago
That is not what I’m suggesting. I’m not saying charging only cables shouldn’t exist. I’m saying what everything does should be clearer.
Disaster@sh.itjust.works 2 months ago
I can’t even find a decent PCIE USB/Thunderbolt card (one that support VFIO would be nice and actually has a Linux kernel driver, so ASM and Renesas are both out…)

Thanks for succinctly explaining what thunderbolt is
KillingTimeItself@lemmy.dbzer0.com 2 months ago
some additional info about USB. If your cable/connector is old, idk how old is requred, the names and standards are actually completely different now than they used to be, but they’re adopted into the new standards, so you have to keep this in mind when trying to recognize this stuff.
thanks USB forum, you guys are the best :)

No symbol for power-only ports?
Crashumbc@lemmy.world 2 months ago
These are found almost exclusively on PC/laptops/tablets. Which I’ve never seen a power port only on.
tal@lemmy.today 2 months ago
Would be nice to have a standard indicator on the cable side of things.
Psythik@lemmy.world 2 months ago
What about red USB-A ports, and USB-C ports with no symbol by them at all (like on phones and desktop PCs)?
ulterno@lemmy.kde.social 2 months ago
On desktop PCs, Depending upon the Motherboard manufacturer and model series, it could either mean nothing other than some gaming marketing jargon or…
When a motherboard has both red and blue ports, the Red ones could be those connected directly to the CPU lanes for USB, with the blue ones being routed through the PCH.
If there is just one red coloured USB A port, it might be designated for BIOS updates (unless they have another colour for that).
morhp@lemmynsfw.com 2 months ago
There is no standard what red USB A ports mean. Could be fast charging through some proprietary protocol or other special features. Or just a design choice.
USB ports with no symbol just don’t advertise what they’re capable of. Most phones support super speed data transfer. Basic USB-PD and display port output support is also common. They may also support other stuff, like pretending to be a webcam, audio output and much more. But you usually have to look in the manual or data sheet to know what is supported.
drathvedro@lemm.ee 2 months ago
On gigabyte boards, red ports were/are signifying their “ON/OFF charge” and “3x power” gimmicks. Basically means that it’s a usb 2.0, with 1.5A limit over normal 500mA, and remains powered when the PC is turned off.
