I tried everything suggested by posters below - and from Luz's guide to no avail....
I then found this gem from this page
IT WORKED! (Please note - I used the sudo nvram boot-args="-v mbasd=1"
as I had already used the original sudo command suggested and it did not work, but I figured I might have already had "boot-args" set as the poster below advises.
Use the Apple external SuperDrive on (almost) any Mac

Thanks, alexburke.
sudo nvram boot-args="mbasd=1"
was great advice - EXCEPT it would have wiped out my previous setting. First, I ran
nvram boot-args
, which showed that I already had boot-args set to
-v
on this MacBook Pro. So, knowing that, I instead ran
sudo nvram boot-args="-v mbasd=1"
which worked like a charm. I rebooted , and the DVD drive was recognized and I was able to burn (an ubuntu DVD-RW) with it.
from there I kept the terminal window open - the drive plugged in - and just restarted. A black screen with code (sorry, I am not a tech head so I don't really know what it all actually means lol) comes up before seeing the apple on restart - and then just restarts as normal. I put in a dvd and it read it perfectly.
