You can't blame vendor creativity on the bus spec.  Look at what the
same vendors do to e.g. SCSI to make these firmwares appear as different
USB devices.  The fact that some of then use "eject" as a signal to
reboot the firmware into some other mode is not a SCSI problem.

But I do agree that USB should have dropped "vendor specific" and
mandated class functions for everything.  In theory. In practice, that
would probably have casued USB to lose to some other competing spec with
vendor specific as an option...
