I think this was at its peak when basically every computer had only USB 2.0 ports. You pretty much could plug in anything to anything, so long as it fit. Not to say there were no issues -- USB 1.1 hubs, cable length limits -- but they were so incredibly minor compared to today. USB 3 introduced blue plugs, complicating things slightly but still everything basically worked, and if something was operating slower than expected it was at least obvious by the color. Then 3.1 and USB-C came out, and apparently USB-IF lots its collective mind. Now you have you pay attention to see if your ports, cables and devices are "USB 3.0" or "USB 3.1 gen 1" or "USB 3.2 Gen 1" or "Superspeed" or "Superspeed 5Gbps".. (Btw, trick question: all of those are the same thing).
