a completely symmetric connection is obviously the best solution, but if they had to have an asymmetric connection, all they had to do was to make the housing correspondingly asymmetric.

in other words, make it obvious by look and touch that there is only one way to plug it in.

consider the 3-pronged grounded electrical connection. that's asymmetric, but it's obvious that there's only one way to connect it, so it's not particularly frustrating. with the current usb design, you're pretty much stuck with trial and error.

Why not before? Because they were such a big improvment over what was used before... JHB Apr 2014 #4
