@futurebird It's frankly embarrassing how long it took me to realize (and by "realize" I mean "notice when reading a Wikipedia article I'd already read before") that USB as a protocol (before USB-C) was designed so that there was a clear side A and side B, and that's why printer cables are Like That™ and also why mini and micro are considered variants of B. And why you never see A to A cables (other than extension cords). Easy to miss when most USB devices had the B side hard-wired in, I guess.
