25-pin din parallel port connectors were D-shaped and invented in the 1970s. And there were directional connectors that long predated that.

USB's rectangular is simply a horrible oversight. Comparing it to PS2 is pretty lame. What about comparing it to nearly every other connector out there?

I'm guessing they didn't want to enlarge the serial port to one almost large enough to stick a deck of cards into.

They wouldn't have to. The point is that the D shape was a proven design at the time, and it (or something similar like the HDMI shape) could have been scaled down to USB-A size.
