I made up a cable according to the instructions given earlier in this thread by KG4INW and it didn't work. Computer didn't recognize the device. So I reversed the data+ and - lines (green and white wires) going to pins 1 and 3 and it worked. So the pinouts for my cable are as follows:

White Data - Pin 1
Green Data + Pin 2
Red Vbus Pin 3
Black ground Pin 4

Looking at the back of the radio the connector facing you the pins are as follows:

Upper left side of the connector is pin 2
Lower left side of the connector is pin 1
Pin 4 is next to pin 2
Pin 3 is next to pin 1

Caveat: YMMV.

If you are lucky enough to have a crimping tool you are golden. if not you will have to carefully use pliers to crimp the connectors or, as I did, solder wires to pins salvaged from another connector.

Have fun.....it's a hobby, remember.
