OK. I know it was way back in July 2012 when you needed this but should anyone else need it here it is.
The USB is digitally isolated with a ADuM1201ARZ But has a USB bridge CP2102 before entering this IC I could go one for hours but the design but if it's a pinout you want.
For the PCB header:
    Pin 1 USB GND
   Pin 2 USB D-
   Pin 3 USB D+
   Pin 5 USB VCC (+5V power must be connected)
It appears that Pin 4 doesn't doing anything (future options maybe) and as all the requirements for USB are found I care not look into it.
So therefore on the LTW 6 pin Mini panel connector (Which appears to be LTWAU-06PMMS-LC7001) the pinouts are:
Pin *1 USB VCC
Pin *2 USB D-
Pin *3 USB D+
Pin *4 Not Connected
Pin *5 USB GND
Pin *6 Pin 4 on header mystery pin
*Pin assignments for the LTW connector I have have given as looking at the male pinned connector (on the panel) starting clockwise from the keyway is pins 1 to 5 and pin 6 being the middle. I could not find anything on LTW pin definitions for this connector without signing up on their site yet again.
Tried and Tested!!!
Enjoy!
