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)
Yeah, it's gotten so bad I eventually ordered a USB cable checker to figure out what any given USB cable is capable of (and to see if the cable has gone flaky, which seems to happen a lot). I haven't received it yet so I don't know if I can recommend this item, but ... gosh darn you sure need something like this.
