i've always thought it was a fairly useless idea
but one day someone brought me a computer for repair...their kid
broke the ps/2 keyboard jack and the machine was unusable
so i put a USB keyboard on it
to get they guy going again
Hmm, comparing to PS/2 one, you should plug in USB device if you are 3 or
103 years old, shouldn't be confused with the mouse port, and shouldn't plug
it rotated by any degree despite the key.
