CD-RW on USB bus (CD-WRITER HP 8200 series)

My CD-Writer on the USB bus appears in dmesg as:
"HP Model: CD-Writer+ 8290 Rev: 1.3C".
It is also seen by cdrecord -scanbus (but I haven't tried writing yet).

To start I would like to simply mount a CD for reading on that external USB drive. I have devfs and I think my USB HP drive shows as:

/dev/scsi/host0/bus0/target0/lun0/generic

This is a CHARACTER device and I think what I need is a block device.
I am very new to devfs. Does anybody have a clue on how to get a CD drive on the USB port working, especially what/if/how to configure devfs and how to mount it in the filesystem?

Or if I use the old style, does anybody know the major/minor device numbers to use with mknod in this case?

have a look into /etc/devfsd.conf and modify it according to your needs.

man devfsd.conf explains all options very nicely.

It turns out that I did not have my kernel configured properly. Disk drives on the USB port are controlled as SCSI devices. I only had "SCSI generic support" enabled, but not, for example, "SCSI CD-ROM support".

With 2.4.20-gentoo-r7 all I had to do was fix the kernel configuration as shown in the following link and rebuild the kernel. The rest just worked (I could ignore the remaining steps in the "tuxmobil" instructions).
