Ffab thanks! I did read the readme (badly) and saw those options but it didnt stop the reporting error. I'm guessing I have to install the driver you mentioned first and then add that line. (My miner is working fine so I dont really want to start messing with drivers as I'm sure windows will mess things up for me if I did!) So will have to just ignore the error repeating. Thanks again! Myrdd.
Wise move. I'm pretty sure that if you installed the driver, you wouldn't be able to use the setup you are using since it would replace the driver you are using. Ouf of curiosity, though, why don 't you want to install the driver and use the device in cgminer (even if a separate instance) instead of running two different miners?
