I just changed a print sentence! The fact is, when I I changed cdrecord
so that it would not write with a dlen of zero the /scanbus command *DID
WORK*. That is why I thought there could be a difference in the
protocol or something that you guys, that know about it, could solve if
I pointed out it had something to do with dlen ...

Alright, I am sending the message I already sent with the output from
the *untouched* cdrecord and pg.c.

But what could it be? I can mount the drive with pcd, and I can see it
with cdrecord -scanbus if I change the code. Just think, cdrecord *can*
get the inquiry information if I skip the 'write() when sp->size zero'
stuff. If you do that you get no error whatsoever scanning the bus and
you get the right information, until you want to write to the CD of,
course, or I wouldn't be writing here :).
