I always thought they were 4-pin. +5V, GND, Data+ and Data- but I am seeing "5-pin". What is the 5th pin and when does it come in to play?

   I have also seen some described "with data transfer" almost as it it were something extra.......

I think you need to check this
The 5th pin is the ID and is used for identification

How about a little more detail? The normal USB 2.0 computer cables have the pinouts as I stated above. So the 5-pin is only applicable to the mini and micro? Are those cables 5-pin on the computer side? What is the ID used for?

Here you are.
The 5th pin defines the kind of device so one is the host and the other is the peripheral.
