I've bought a USB OBD cable from BMW cables on fleabay. I've set it up and if I remove the cable from the laptop both black indicators go out but as soon as I plug it in both indicators turn black without it being plugged into the car. I'm trying to work out if I've got a faulty cable or screwed up the com port settings so if anyone nearby has the same setup i'd really appreciate swapping cables to see which it is....
Thanks!
