Yes I did. But with the 2.3.99-pre7-2 kernel I'm getting some better
results, I'll describe them here. The bottom line is: the USB device is
recognized now (as being a mass storage device), scsi commands are
issued to interrogate the device, but I fail to mount any of the
/dev/sd* or /dev/scd* devices (I tried all of them w. xargs). There
does not appear a scsi devices in /proc/devices but I'm not sure if
it should.
Relevant modules that I've loaded: usb-storage, uhci, usbcore, scsi_mod
and isofs.

The USB storage scsi bridge also seems to be functioning properly:
# cat /proc/scsi/usb-storage-0/0
Host scsi0: usb-storage
Vendor: Shuttle Technology Inc.
Product: HP USB CD-Writer Plus
Serial Number: None
Protocol: 8070i
Transport: Control/Bulk
GUID: 03f001070000000000000000
However, I cannot mount any scsi device. When I cat /proc/devices, there's a
usb device at major 180 (is this /dev/bus/usb?) and nothing more that looks
like usb or scsi. When I cat /proc/scsi/scsi, then I see that there's a
host scsi0 with the following devices:
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: HP Model: CD-Writer+ 8200 Rev: 1.0f
Type: CD-ROM ANSI SCSI revision: 02
for Lun = 01 to 07.
I echo'd "scsi add-single-device 1 0 0 0" > /proc/scsi/scsi but perhaps I
didn't do this at exactly the right moment (do I have to do this before
physically attaching the USB device?)

When I try to mount:
# mount -t iso9660 /dev/scd0 /mnt/tmp
mount: /dev/scd0 has wrong major or minor number
# ls -al /dev/scd0

same for scd1 and all sd* devices.
