User is member of operator group. However, I agree with your idea because
just now I was working with cdrtools and got this error, but when I ran as
root no error:
% cdda2wav summary --device /dev/cd0
cdda2wav: Permission denied. Open of /dev/xpt0 failed. Cannot open or use
SCSI driver.
cdda2wav: For possible targets try 'cdda2wav -scanbus'. Make sure you are
root.
Probably you did not define your SCSI device.
Set the CDDA_DEVICE environment variable or use the -D option.
Regards.
