I just tried a micro USB cable soldered directly to the board, with the proper wiring, (from left to right with USB side of board facing you ... pin 1 red V, pin 2 white data -, pin 3 green data +, pin 4 black ground) but could not charge with it. All voltage readings are correct as per MB project page. Same for the micro USB plug. All good. I tried the data -/+ shorted and open, but had no luck. I removed the plug and installed the USB jack, and it works like a champ. I have checked continuity on the cable, while soldered to the board, and after removed from the board, and all the wires are good.
Oh, I tried charging a Razr, a Razr Maxx, and a Droid X. All 3 will charge with the jack on the board, but none will charge with the cable on the board.
Is my wiring wrong? Any ideas?
