Knowing the difference between a keyboard and a mouse was stretching the

That's one of the minor issues. But the main point is that PS/2 was
specialised anyway - can only deal with a narrow set of devices, and is
fickle about those, while USB lets you connect virtually anything
(handwaves details) so the potential exists to reduce the number and
diversity of sockets. That's my opinion, anyway :)

They had different shaped connectors. They color coded them!
Eventually, they just gave up and added an extrea microcontroller for
each, just so that people didn't have to insert the plugs into the jacks
that fit.
