on a r/h machine that works:
orch:~> cdparanoia -Qsv
cdparanoia III release 9.8 (March 23, 2001)
Checking /dev/cdrom for cdrom...
Testing /dev/cdrom for cooked ioctl() interface
/dev/scd0 is not a cooked ioctl CDROM.
Testing /dev/cdrom for SCSI interface
generic device: /dev/sg1

notice the /dev/sg1 "generic device"
