I saw that linux 2.2 sends a TEST_UNIT_READY, and, after, a INQUIRY.
There's any reason to do this? Also, my CD-R keeps reseting the scsi bus
when it is probed for LUNS !=0, this may be the cause? (Adding it to the
blacklist resolves my problem).
My CD-R is a SONY CD-R CDU926S Rev 1.1e (as I got from /proc/scsi/scsi),
connected to a Adaptec AHA-2940.
