[CentOS] Unable to mount a USB DVD drive

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?
