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 

See the man page for more info on using kextunload

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.
