   Somehow an old mouse or keyboard adapter was still laying around that should   
   have been tossed back in the early big banglocene so I cut it open.   
      
   It had 5 wires:   
      
   brown   
   yellow   
   red   
   green   
   uninsulated.   
      
   The 13.3 mm dia. male connector had 5 pins.  For orientation it's an octagonal   
   configuration missing the 3 top pins.   
      
   From left counter clockwise the wire order was:   
      
   brown   
   yellow   
   red   
   green   
   nc   
      
   The 10 mm dia female connector on the other end had 6 holes hexagonal.  For   
   orientation the rectangle was below the top of the circle of round holes.   
      
   nc   
   green   
   nc   
   Red   
   yellow   
   brown   
      
   Ignoring the nc pins, this is the same order for the 10 mm male.   
      
   Is there some kind of convention where they try to get the same order for all   
   4 or 5 wire round connectors?   
      
   The M8 male going to a device has, going counter clockwise from power to   
   ground:   
      
   +5v power   
   nc or data (+ or -)   
   data (+ or -)   
   0v power   
   nc or data (+ or -)   
      
   The first guess is that it's:   
      
   +5v power   
   data (+ or -)   
   data (+ or -)   
   0v power   
   nc   
      
   If that doesn't work (or fry everything) try swapping the assumed data lines.   
      
   If that doesn't work (or fry everything) try:   
      
   +5v power   
   data (+ or -)   
   nc   
   0v power   
   data (+ or -)   
      
   If that doesn't work (or fry everything) try swapping the 2nd assumed data   
   lines.
