removing integration features

Does anyone know how to remove the cubase integration drivers in MAC OSX? There are just too many instances that Cubase doesn’t grab complete control of the unit and the routing doesn’t function properly until I do a system reset. I’d like it to function as a normal sound interface where the GUI doesn’t disappear when I open Cubase. I know this is possible but haven’t found directions.

Using UR824 and UR28M

Mac OSX 10.8
i7 3.5
