Sorry...but that's simply not true.
From
this source: "The USB 1.0 debuted in late 1995 and transferred data at a rate of 12 megabits per second.".
Wikipedia states it as January 1996, but seeing how USB didn't became a standard for years that isn't exactly wrong (I bought my first own computer in 1999, and specifically picked one that had USB because I had read about it in magazines...things like PC and mouse still used PS2 as default back then).
Release date playstation 1:
late 1994 or 1995, depending on regio. And it's safe to say that the design of the thing probably took a couple years before that.
