External HP dvd writer not detected

Hi, I'm trying to install an external HP DVD writer (model: DVD420e) on Mandrake 10 with Kernel 2.6.3-7mdk. The DVD writer is connect trough an usb2 port on a PCI card. Here the line from lspci showing my usb2 controller:
00:10.3 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 82)

My problem is that the DVD writer is not showing anywhere. I have looked in dmesg, in lsusb, in fstab, in the /mnt and /dev folder but I couldn't find it. Here what I got from lsusb:
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 03f0:7104 Hewlett-Packard
Bus 001 Device 002: ID 05e3:0604 Genesys Logic, Inc.
Bus 001 Device 001: ID 0000:0000

The Hewlett-Packard on the second line is my usb printer who is working fine. But I have no idea what the Genesys Logic his.
And here is my fstab:
/dev/hda5 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hda7 /home ext3 defaults 1 2
/dev/hdb /mnt/cdrom auto umask=0,user,iocharset=iso8859-15,codepage=850,noauto,ro,exec 0 0
/dev/hdd /mnt/cdrom2 auto umask=0,user,iocharset=iso8859-15,codepage=850,noauto,ro,exec 0 0
none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=iso8859-15,sync,codepage=850 0 0
/dev/hda1 /mnt/windows ntfs umask=0,iocharset=iso8859-15,nls=iso8859-15,ro 0 0
none /proc proc defaults 0 0
/dev/hda6 swap swap defaults 0 0

The first cdrom is an internal LG CD-rom and the second cdrom is an LG CD-rw.
The only place that I can see my DVD writer is in my bios. It the first time I use linux and I really don't know what is should try to detect it.

I have a similar issue with a different HP External DVD writer. I contacted HP customer support thinking that since they are a big player in Linux systems they might know how to resolve. I got a disappointing answer. They claim that none of their external DVD writers will function on Linux OS. Something about an MMC interface (what ever that is). After going through this site and a couple of other searches my guess is that no one really has these external DVD writers really running on Linux yet... too new.

thank you for your answer

I have also e-mail hp support for the same reason as you do and weirdly they told me that it was possible to fix it but that they didn't have a linux driver and that I would have to find one on a Linux support website. They also told me that I need a program that would be able to detect the dvd. I'm still looking around the net hoping to find something to fix it and at worst I learn that in my computer science class we are going to learn how to install and configure linux, so maybe I'll get a solution from there. Anyway, thanks you for replying to my post.
