Well, there seem to be a number of drives that don't like probing higher LUN numbers, and there was not much need for them, until now ... The driver deals correctly with LUNs, and you should be able to just increase the MAX_LUN parameter. This should really be controlled from the generic SCSI code, and I have got ot admit, that I don't remember why it is not implemented that way, currently. (There is some extra RAM required per LUN, but this should not be much of a problem ...) If somebody sends me such a drive, I'll make sure it works!
