I'm very new to Linux and Knoppix so please forgive any Newbie questions

I'm using a recent Knoppix Cd, downloaded and burned sometime in early January 2004 on a Dell Inspiron 7000 laptop, plugged into a Dell Port Replicator with 2 USB ports. I'm unable to find my external Buslink Model L40/40G HD under Knoppix using either USB port. I've tried looking with Fdisk -l, Applications-->Tools-->USbView and even gave a shot at Mount but it said the USB was already mounted. My USB Smart Card reader running off a Belkin USB 4 port hub works, I can plug it in and it works, take it out and it dissappears from USbView

I found a link to a user supplied Driver at http://www.qbik.ch/usb/devices/showdev.php?id=605

My questions are
1. How can I determine if this driver is installed in Knoppix

2. If not, how do I install it into Knoppix running off the CD. It's probably wise to mention that I have to use the boot floppy because my BIOS won't recognize my LITE-On CD-RW

3. Is there any thing else I could try

Thank you
