I think this is what they do, as my test with a multi-LUN CD changer which works find as a SCSI device only shows up as one CD-ROM under both Windows and BSD. Time to hit up Microtech support to see if they'll at least admit that this is what their driver does. The question then is if we are to implement this kind of ID-to-LUN mapping in the umass driver, what do we predicate that behaviour on ? -- j. James FitzGibbon james@targetnet.com Targetnet.com Inc.
