Try locating with dmesg.
From the command line.
Code:
%dmesg | grep cd
acd0: CDRW <LITE-ON COMBO SOHC-4836K/SPJ2> at ata1-master UDMA33
%
The example is from FreeBSD but the command line will get the same results.
You may also want to look for hdc in /dev.
Try inserting media and see what syslog puts out.
Find the manufacturer of the drive and use that for the driver.
