On the machine I usually burn CDs on,

ahc0: <Adaptec aic7880 Ultra SCSI adapter> rev 0x01 int a irq 9 on pci0.13.0
ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs
.
.
.
cd0 at ahc0 bus 0 target 2 lun 0
cd0: <HP CD-Writer 6020 1.07> Removable CD-ROM SCSI-2 device 
cd0: 3.300MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Logical unit not ready, cause not reportable


And I get the following,

# cdrecord -scanbus

Note that cdrecord version change _fast_. I just looked and I see we
at least to 1.8a29.

I had a look at the source... non-trivial matter to figure out what
device it is trying to open. It would be nice if the error output
actually said. Maybe hack the source to get that output.
