    I'm have a tough time getting the ECM cable purchased directly from xopti to install correctly on my Win8 laptop.

    I've gone to the Prolific site and downloaded the latest drivers and the cable appears to be installed in device manager, but is shown with a yellow exclamation point. Checking the properties of the device, it lists the following message:

    This device cannot start. (Code 10)

    A device which does not exist was specified.



    I'm pretty much stumped as to what to do to clean it up and get it working. Any ideas?

    My advice.. Buy Windows 7 and upgrade from your current POS 8!

    My new laptop had Win 8, after 4 months I couldn't handle it anymore and "upgraded" to 7.

    Never tried ECM SPY on 8, but works on 7.

    I can understand your sentiment. I find Windows 8 to be pretty solid (once a start menu is added back), and I need this machine for work. I don't think it's necessarily an issue with windows as much as the ****ty Prolific chipset and drivers. I have Win7 available and could even create a VM with XP on it to do tuning, but it seems archaic in this day and age.

    Does anyone have this combo working?

    Okay... I got it working. The key was to install the correct (usable driver) first, let Windows Update update the driver, and finally, via the device properties, rollback the driver to the one which was installed in the first place.

    If anyone needs a working Prolific USB-Serial driver for Win8 for Xoptiinside's ECM cable it is the Windows Vista driver set that matches the cable's version.

    I guess it was just the next available number. I swapped it and the Intel AMT, so the cable is now COM3 (though that wasn't the issue).
