I've run into the same problem as this guy [closed-no answers]: UBUNTU isn't recognizing the dvd/cd drive
I recently installed 12.10 (32-bit) on a HP EliteBook 8560p. I used the ODD (CD/DVD+RW) to install the OS.
In the OS, I then insert a CD or DVD (data disks, not audio/movie). Nothing happens. I don't see anything from lshw, dmesg, or syslog.
What else should I look into? Since at least one other person has/had this issue I know that it's not just me.
