I just looked back onthis thread and noticed that you are using ULM-20 lamp modules. Those are not supported in any of the drivers. I was able to hack in a couple of switches and modules to the original drivers ages ago. But I don't know if I can add anymore. I am NOT a programming guy.
Bottom line, if they device is not specifically listed in the driver, the system won't find it. HOWEVER, it should at least show as an unknown module. So if you don't have that, something else is wrong.
Go to the Simply Automated website and download the UPBStart software. Install it. Stop the Premise service. Run UPBStart and see if it can find all of the devices. Program them to have the same network ID, give them names, etc. Then shut down UPBStar and fire up Premise again and see what you get.
