Sorry, I should have clarified this earlier--the Quantum GoVault is a removable disk drive, not a CD-ROM. The device is reminiscent of Zip disks, but the cartridge is a sealed unit and contains a 2.5" SATA disk inside; hence it's not a CD-ROM. So the patch below won't work for me, because sdev->type == TYPE_DISK.
I wonder if the same sort of REPORT LUNS screw-up might apply to other ATAPI devices too, such as tape drives. Since we've seen that manufacturers of CD-ROMs and removable disks don't implement it, it would not surprise me if the other ATAPI devices don't either. But, that's speculation on my part.
