Haa, OK. I thought INQUIRY EVPD=1 page=0 was so old it sure must be supported
but you are saying it's only SBC2/SPC3. So I guess there is nothing else we can do.
What I hate about all this is that in USB the scsi_level is hard coded at the driver,
without actually been able to probe the device about it. So my 1 TeraByte new seagate
external disk must behave like the above junk.
(Thank god for eSATA)
