I just received my pro-668 and it's running fine, I connected it to my computer and ran all the software then did the firmware up grades everything seems to be fine. I have a question though when i'm looking at the main configuration page on my computer and make changes they are not sent to the scanner and there is no button to send the new configuration, for instance I can change the scanner volume from the scanner but it doesn't change when I do it from the computer. I have tried everything I can think of. can someone answer how it's done?
