You won’t find these symbols on most devices though (certainly not on any macbook as the picture suggests).
By removing the symbols they were able to shave the case down 0.0003nm, making it the thinnest and lightest laptop ever.
It gets even better, each function of the port also needs proper support from the cable. Often cables do not support the full spec of usb to cut costs.
While the symbols in the post are often put on computers, for usb cables this is seldom done (only a few brands do).
Source: had to find a cable that supports both DP and PD to connect a portable external monitor after I lost the original cable. (1/9 cables worked)
TL;DR: The USB Implementers Forum is ridiculously bad at naming, symbols and communication in general. (And they don’t seriously enforce any of this anyway, so don’t even bother learning it.)
This is the correct answer; after the whole USB 3.2 Gen 2 2x2 (hands of blue) bullshit, I wouldn’t trust that team to name a park bench in the middle of the desert. Let alone something important and universally used.
We could have gone for already proven and tested conventions like the resistor color codes and have a unique distinguishable icon for each features to attach when needed (like thunder icon for high power). But nope, we got this
USB 3.2 Gen 4 2x2 Hyper Turbocharged World Champions and Knuckles Platinum Editionbs instead.
