as per NUT HCL, Comet Extreme use the UTalk protocol.
so mge-utalk is the driver you're looking for.

the above message shows that the mge-utalk driver can't start since there is
another driver locking the port.
so, first, stop everything, and issue a "killall mge-shut mge-utalk"
then start NUT as usual.
if something really goes wrong, stop everything and then try starting
mge-utalk in debug mode, to see if there is actually a problem, using:
$ /path/to/mge-utalk -DDD -a MGE_cometEX

Let it run for 30 seconds, and send us the output.
