@jacob: led is red, why?
Must be Green. You power-up the cable? (+12V between pins 16 and 4 OBD2 or plugged in a car).
If not, that's the problemm.
And if LED is red when connect at usb, the cable is cheap and bad.
Few photos with both sides of PCB, good resolution.
@dadymee: loader is a little programm used for some versions of VCDS.
