For reference:
I first tried using the drivers provided with OpenEcu 1.29a for the cable. These worked fine with RomRaider's logger - but while OpenEcu would recognize a cable was connected by the read button being active it, would tell me that it was unable to connect to OpenPort. I uninstalled the drivers and tried the ones linked to on the first page here with the same results, ensuring correct baud rate and trying several different ports
So, I uninstalled the drivers from the port and uninstalled OpenEcu 1.29a. I installed OpenEcu 1.42.2595, at the time most current, and its openport drivers. Rebooted, and OpenEcu was able to read my ECU without problem!
This is using the blue connector with silver wire cable
EDIT:
Successfully flashed new map with latest version of OpenECU and logged with RomRaider without issue
