This is not quite the right place to ask this question, as
cdrecord is an application maintained by Joerg Schilling,
not by members of this mailing list. The correct place
to ask questions about cdrecord is .
However ...

Most likely you want to say dev=0,0 - unless you also have
a SCSI controller on your system. The more general answer
is to read the cdrecord documentation and do

        cdrecord -scanbus

And use the output to construct the dev= parameter. (Alas,
I don't think Joerg prints the scanbus report in the same
syntax that he expects for the dev= parameter, but you
should be able to figure it out.)

BUT, it is also possible that your cdrecord was not
compiled correctly. If pg loads successfully and
cdrecord -scanbus doesn't find the drive, then something
is wrong with your cdrecord. You can load pg with the
extra option "verbose=2" to get a trace of all commands
that the driver processes (on your console - don't do this
in X). If cdrecord isn't even probing the pg devices,
your local configuration is probably not correct: the
cdrecord makefiles expect to find pg.h in a correctly
linked kernel source tree, else they silently disable
the pg support.
