Standard USB Pinout Looking at a
standard A plug head on with pins up,
the pins are numbered backwards from 4
to 1. Pin 4 is the -5 volt lead, pin 3
is the + polarity data pin, 2 is the -
polarity data pin, and pin 1 is the +5
volt lead. Standard B plugs are a bit
different due to shape. The plug is
square, with bevels for the top
corners. There are two pins on top,
and two pins on bottom. The order is
clockwise starting top left, 1 through
4. 1 is +5 volt lead, 2 is + polarity data, 3 is - polarity data, and 4 is
-5 volt lead.
