Also a male USB 2 plug fits perfectly into a RJ45 slot :-/
In my days of tech support, I’ve seen multiple people plugging their USB printer cable into the network slot of their computer and it’s a perfect fit so they were always convinced they didn’t do anything wrong…
That’s clearly a design flaw while all other connectors have distinct sizes.
Way back before USB, joysticks had a DIN-25 connector that was identical to the MIDInetwork connector.
I blindly plugged my brand new MS Force Feedback joystick into the MIDInetwork port behind my miditower (yes I’m that old) and watched the magic smoke rise out of the joystick. That was not a good day to learn about plugs. The network carries 50 volts or something. Stick wasn’t happy.
AFAIK the real predecessor to USB was Serial cables and those were an absolute shit show. USB set out to create a more usable interface with a lower profile and cheaper cost. In many ways the minor flaws in USB becoming common gripes is USB becoming a victim of its own success. I don’t think they originally set out to become a power charging standard so the frequency at which devices were plugged in increased over time .

This is a most excellent place for technology news and articles.
TL;DR: its cheaper that way,
And i value that decision
New question: why did it have rotational symmetry?
Because fuck you that’s why
Oversight
Cheaper. Any other questions?

How lucky you were to never have a device that had one of these upside-down.
Or a printer with the B connector rotated 90° to one side.
Hindsight is 20/20. You’re raising every issue with the original USB plug, then proceed to highlight how they addressed these issues going forward.
You’re describing inexperience and calling it incompetence.

At least serial cables weren’t symmetric, although just barely. AT and PS/2 cables (or any DIN) were much more of a pain for me to plug in blind.
