I wasn't actually proposing that you run that way, only that you try connecting that way to help determine if you are having a driver problem or an Astroart problem. If you can connect to the two cameras from two different applications (or two copies of the same application), that would show that the driver was working correctly and that we need to look at astroart to figure out how to make it do what you want. If you cannot connect to both cameras , then it is probably a driver problem and I'll have to tell you how to create a log file.
