I picked up one of these:
Off ebay a little while ago, but I've not been able to get it working. I've installed a slew of drivers and software iwth no success. In my device manager i have USB Serial Port (COM7), but that's it. If anyone has gotten this one working can you please tell me now? I've searched all over with no success. If it makes any difference, I have an 04 Ford Excursion with a 6.0 diesel.
