[paranoia] No generic SCSI device found

[Bernie Boudet]

Hi,

I'm getting the error "No generic SCSI device found to match CDROM device /dev/scd0".

I have read the README and the FAQ, and I still cannot see what could be
wrong.  Any help would be very much appreciated...

My system:

    Debian 2.2 with a stock kernel,
    Ricoh MP6200S scsi re-writer, firmware rev. 2.20,
    Adaptec 2940UW scsi interface,
    There are no scsi hd's.

The MP6200 is /dev/scd0, there are no hardware probs AFAICT because this
device mounts to /cdr without problem (it is not mounted when I try
cdparanoia).  There is an audio CD in the MP6200 and the cddb info has
been read off that so I guess this is ok too.  

/dev/cdrom points to my IDE cdrom, which gets mounted as /cdrom, but
also not mounted at this time. 

According to the FAQ, I need to load the sg module (done that), create
the /dev/sg? devices (done that too) and the /dev/sr? devices (already
there), and have read permissions on the drive (I am in the cdrom group).

I've pasted as much detail as I can think of below, please ask for
specifics if I missed anything:
