My TEAC R55S SCSI CD-Burner works fine with Fedora Core 1.
cat /proc/scsi/sg/devices

TinyDisk 2003-10-10 2.00 TEAC CD-R55S 1.0R
Fedora Core 2 also recognizes it at /dev/scd0 (CD-reading works fine). But cdrecord, only regognizes my ATAPI-CDROM, which isn't a CD-Writer:

I have tried serveral former Versions of cdrecord (also the one included in Fedora Core 1) whitout success.
The main problem seems to me, that there are no sg-scsi-devices:
cat /proc/scsi/sg/devices cat /proc/scsi/sg/device_strs
...no result
I can find the CD-Weiter in the sysfs:
cat /sys/bus/scsi/devices/0\:0\:3\:0/modelCD-R55S
cat /sys/bus/scsi/devices/0\:0\:3\:0/vendor
TEAC
So, were are the /dev/sg* - devices? And why doesn't find cdrecord the SCSI-Device?
To resolve the problem. I made a link:
ln -s /dev/scd0 /dev/sg0 cdrecord --scanbus
scsibus0:
