Among my mini & micro USB devices, I have a Motorola RAZR that I want to charge in my 2.1 Amp USB car cigarette adapter.
Everything charges with this setup EXCEPT the Motorola RAZR V3.
Digging into why, apparently Motorola uses a 5-wire cable instead of a 4 wire cable.
How do I find a 5-wire USB2.0-to-mini-USB cable?
Googling, I find tons of cables, but none SAY how many wires they have.
What you need is one of these which they no longer sell. It modifies the Mini USB connector so the phone will charge from a standard Mini USB charger or USB-A to Mini-USB cable. I've used these successfully.
If you could find a Mini USB cable with five wires you could modify it as described at but you're unlikely to find such a cable unless you cut one off of a Motorola compatible car charger (not sure if the resistor is inside the Mini USB plug or inside the charger).
If a USB port shuts down because of too much current draw, would it turn itself back on after a delay? If so, what is the delay in seconds? If the port does not reset, what does the user have to do to reset the port?
