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?
