kernel modules/drivers are specifically compiled for a kernel (-versions) and even distributions
it's not like windows where you can download a driver somewhere and just put it in
so don't take any *.ko file, stick it in and expect it to work
if you haven't build the *.ko yourself or don't know exactly where it came from, expect it to fail
I'm no expert but as there is no how-to here in the forum - lets start one
hopefully other will correct and help refine or take over
