Quoting myself here, I have learned that yes there are indeed special characteristics of the USB export function. This is solely based on my attempts to export out of an existing controller onto a USB and observing the file structure. It is vastly different than just a ulpr file. Everything seems to be packaged quite separately in the USB export dump, and the configurations seem to be split into many files and folders of varying types. It doesn't even appear that I can back into these files by exporting individual components out of unilogic either because the file structure is so different. So it appears I'll be forced to install the software I need onto a different laptop so I can create this file.
