Kextual Healing: How can I remove Kexts that appear on startup?
See this Apple Support Communities thread - it addresses your exact problem (specifically, this response). 

If you still have issues, prevent the kext from loading by using sudo + kextunload instead of kextutil. For example: 

sudo kextunload /System/Library/Extensions/BJUSBLoad.kext 


kextutil would be appropriate for debugging purposes (corrupted, missing dependencies, deprecated, etc) in the hopes of repairing it. kextunload is the tool you are looking for - see the man page for more info on it.
