USB is emulated through the SCSI layer, tho.

We assume it's coming from the SCSI system, as usb-storage doesn't contain anything remotely resembling this.... Repeated uses of the 'eject' command generated the same sequence in his test scenario, but his Zip 100 actually ejected the media on the second try. I think that's a device-dependent behavior, tho.
