I can't seem to get an external DVD drive to show up on an CentOS 7 server.
Wondering if it's just missing a driver or if I'm missing something
fundamental.
It's an external USB device that works fine on my Fedora 21 Laptop, but I never
get a /dev/ entry (EG: /dev/sr0) on the server.
What can I do to make this thing work?

This is what tail -f /var/log/messages looks like on my F21 laptop:
