and after this- you will see that the scanner driver asks the same question over and over again, with the only change being the LUN. That may be a leftover from the days when the driver was used on actual scsi scanners, or it may be a means for the scanner to expose the existance of different sub-components. in all likelyhood, you can leave them out. allan > its like the matrix. eventually you dont see the code anymore :) > > allan > > -- "so don't tell us it can't be done, putting down what you don't know. money isn't our god, integrity will free our souls" - Max Cavalera
