Hopefully someone can point me in the right direction.

What the heck is going on?  The device is there.  Dmesg shows that the 
kernel knows what it is.  Yet I can't read or write cds, and, as you can 
see, camcontrol thinks it's non-existant.  Yet cdcontrol will open and 
close the drive but can't provide any info???  What am I missing?
