Q: Unseuccessful 'sudo kextunload' while looking for Kernel Panic cause

Trying to figure out what's causing Kernel Panics after testing Logic Board, Hard Drive and resinstaling OS X with a clean  internal drive ...

This is what Im getting attemptin to do 'sudo kextunload'  :

host-001:~ ruzzonmatteo$ sudo kextunload /System/Library/Extensions/DigidesignMbox2.kext

(kernel) Can't unload kext com.digidesign.mbox2.driver; classes have instances:

(kernel)     Kext com.digidesign.mbox2.driver class MaudioShDrRayUsbEngine has 1 instance.

(kernel)     Kext com.digidesign.mbox2.driver class RayEngine has 1 instance.

Failed to unload com.digidesign.mbox2.driver - (libkern/kext) kext is in use or retained (cannot unload).

host-001:~ ruzzonmatteo$

Not sure what's going on there
