Default Do they make a Motorola RAZR 5-pin USB 2.0 to mini-USB cable?

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.

Google specifically for [ Motorola USB charging cable ]. The first page of
hits has plenty of sources (even for under $3 a pop), wiring diagrams, etc.

If it works with the V3, it's only because the CABLE works with
the V3 because the Motorola Razr is NOT standard USB even though
the connector LOOKs like a mini-USB connector.

What you need is one of these
http://dx.com/p/mini-usb-power-connector-for-moto-v3-32583 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
http://pinouts.ru/CellularPhones-A-N/razrv3_charger_pinout.shtml 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).

I was worried about that RESISTOR!

Nobody mentioned it, but you - but I did see the resistor in the original
specification!

So, can you confirm that simply getting a 5-pin cable won't help. Right?

It has to be a 5-pin cable with the Motorola-sized RESISTOR in it, right?

That's correct. But it's the wrong question. The USB-A side is only four
pins so a cable with a five pin Mini-USB plug will have only four wires,
there's just no place for the fifth wire to connect. Unless it's a cable
specifically designed to solve the Motorola problem.

On the Motorola chargers, it's a five wire cable into the charger where
the resistor is located.

Try this cable: http://www.thecellguru.com/Products/5974.

Have you contacted Motorola to find out /exactly/ what cable is needed?

I believe the resistor is needed to "clue" the power supply that something
that "wants" to be charged is connected.

Cables are cheap. I'd buy one and see what happens.

By the way, the USB-cabled charger for my Samsung cell phone will also charge
my Garmin GPS. Very handy.

I'm confused because I just tested a "normal" cable and this was
my observation:

Motorola RAZR V3 connected to wall-wart USB charger -- fail
Motorola RAZR V3 connected to automotive USB charger -- fail
Motorola RAZR V3 connected directly to Linux PC -- charged!

The weird thing is that I used the same cable for all 3 tests!

I'm sorry - but I'm still confused, especially after reading one of the
reviews at that web site which said "This cable works to charge my
Motorola Razr v3 from a USB port without needing the Motorola charging
software."

To my knowledge, I don't have any "motorola charging software" on my
Linux laptop - but I just plugged in a standard mini-USB cable (USB 2.0
on one end, mini-USB on the other) and it charged the Motorola RAZR V3.

Then I took the exact same setup, and plugged it into a wall-wart USB
charger, and it failed. Likewise with the cigarette lighter USB charger
in my car.

Clearly this cable does NOT have the resistor (it's a generic USB cable),
and I don't know that motorola phone tools was ever installed. Looking
on my system (using updatedb) I see there are "some" files with the
word "motorola" in them, e.g.,
/usr/src/kernels/2.6.32-279.1.1.el6.x86_64/include/config/usb/serial/
motorola.h

But, no specific motorola software seems to be installed - yet - the
4-pin cable is charging the phone. How is that?
