Thanks, that helped. The verbose output gets the unique IDs sorted out. I'm still working out some of the kinks. It looks like there is an issue with Windows not always recognizing the Geek.Pub controller at power up. Unplugging and re-plugging the controller seems to work. Not very elegant, but at least I am making progress. Now I just need to get back to getting Launchbox working.

Sorry, should have included the link. Controller Configuration Files — MAME Documentation 0.252 documentation (mamedev.org)

I'm looking at the MAME documentation as I have the problem of controllers reassigning their order when the system is power cycled. I found the section that talks about how to do that. But I don't understand "where" I'm supposed to make the changes. I see the controller folder with a few different controller types. But I don't see anything that looks like the xml format that the guide talks about. Where is the area that I add the device IDs to? Probably obvious, but I'm just not finding it... 😕
