PS/2 is a special case of I2C and USB is based on I2C. So the principles 
share on similar ancestors.

USB = power + balanced clock/data
PS/2 = power + unbalanced clock/data

See http://en.wikipedia.org/wiki/PS/2_port and 

The last USB specification I saw took up 500 double sided A4 pages to 
describe the hardware and the protocols. At that moment I gave up.

That is impressive. But only when you stay in motels and live in a place 
that does *not* look like one giant electronics commercial (like Europe 
or the US).

I may have one in a desk drawer. Or I get one around the corner. If you 
cannor find yours I will mail one to a friend. If I have an address. You 
seem to be living 'rather remote' (i.e. not surrounded by 20 stores in 
the same 1 sqm grid).
