Hi-Val external usb-2 cd-rw atapi (made by Acer) is recognized when I run from the knoppix cd if the cd-rw is turned on at startup. An icon appears on the desktop, and the kde control center usb shows it's there, and I can read a cd which is in the drive.

I have installed knoppix and tried to get it to recognize the cd-rw using the same /etc/fstab setup which appears when running knoppix cd, and several other configurations of /etc/fstab and /mnt.

The cd-rw does not appear in the usb part of the kde control center. USB ports are recognized.
I would like to be able to access the cd-rw from a desktop icon, read and burn cd's.
Any help appreciated.
