I think you're confusing "server core" and the "lubuntu-core" package. 
Lubuntu doesn't have a server edition.

  So, my impression was a server system is a bit more raw and basic than 
a desktop system and going with a "core"

lubuntu-core is indeed a very minimal Ubuntu install with a minimal LXDE 
desktop environment. It's my current preferred way to set things up, 
first do a minimal Ubuntu install and then install the lubuntu-core 
package and move on from there.

Which software and variables are you referring to?

  It's just the first time the (Presonus) Audiobox has not initialized

What did you actually install? What is the output of uname -a on the 
machine on which the Presonus doesn't work?
