Same on my FreeBSD 8 home system:

% ll /dev/cua*
crw-rw----  1 uucp  dialer    0,  49 2016-10-10 23:49:07 /dev/cuau0
crw-rw----  1 uucp  dialer    0,  50 2016-10-10 23:49:07 /dev/cuau0.init
crw-rw----  1 uucp  dialer    0,  51 2016-10-10 23:49:07 /dev/cuau0.lock

It probably has happened somewhere in v11... The Thinkpad laptop
running 10.3 I have here, connected to the "dock" with a serial
port, also shows the cucu0 device similar to your listing.

Maybe the cuad0 port gets created dynamically somehow? In fact,
I cannot remember having seen cuad0 anywhere... even worse, on
older FreeBSD versions, cuaa0 was the port name used for modems
or mice, if I remember correctly...

So maybe it's just a "multi-typo"? ;-)
