Hi,
I am not an expert but your problem seems to be this:
you have two ways to access your SCSI CD-ROMs:
through a "generic" interface and a more specialised
"cd" interface. In some CD-ROM related software
(cdda2wav I think is one) there are options allowing you
to specify which interface the program should try to use.
However these interfaces should be compiled in your kernel
or the corresponding modules should be inserted.
In one of my previous setups I had the SCSI CD-ROM support
compiled in, and I had the generic SCSI support as a module.
When I started my system and checked the devfs tree, under
/dev/scsi/host1/bus0/target0/lun0/ (numbers may vary) I had
an entry named "cd" (a block device) and this one could be
used to mount a CD with an ISO9660 filesystem, or to play
an audio CD.
I could then "modprobe sg" and then another entry named
"generic" appeared next to the "cd" entry (I don't know if
it is a block or a char device). As I remember it was not
explicitly needed for CD writing as Jorg Schilling-s
programs use his special library instead of kernel
support...
Anyway, the point is that you certainly need to:
- have SCSI CD-ROM support in your kernel
- use (or link to) the devfs node "cd" instead of "generic"
Hope the above explanation and hints help.
Confirmation and/or corrections welcome. I may not know what
I am talking about.
