[Soci SLIP] errore con masterizzatore

[luca]

non riesco a creare un immagine di un cd con k3b, ho letto diversi bug.. ho
applicato i suggerimenti ma non riesco a farlo funzionare comunque
il log dell'errore è questo:

/usr/bin/readom: Device or resource busy. Cannot open '/dev/scd0'. Cannot open
SCSI driver.
/usr/bin/readom: For possible targets try 'wodim -scanbus'. Make sure you are
root.
/usr/bin/readom: For possible transport specifiers try 'wodim dev=help'.

usando il comando suggerito esce fuori questo:
# wodim -scanbus
wodim: No such file or directory. 
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

l'utente che lancia k3b fa parte del gruppo cdrom, i device usati dal
masterizzatore hanno come proprietario root e come gruppo cdrom

ho persino modificato il nano /etc/initramfs-tools/modules aggiungendo questi
moduli

piix
ide-disk
ide-cd
ide-generic

e upgradando initrams...
ma nulla di nulla
su altro portatile stessa storia, stessi non risultati

ho provato da line adi comando a dare prima
# readcd -clone -v f=cdimage
per creare un immagine e poi scriverla su disco vuoto con questo comando..
cdrecord -raw96r -clone -v driveropts=singlesession,burnfree ./cdimage
con questo risultato
