True, this is for backward compatibility; the /dev/sga,b,c sequence is deprecated. > Also most harddisks will respond at every LUN. I hope not. Could be a problem in lk 2.5 where we support 64 bit luns :-) > Once again, I can't see any reason why probing all LUNs will prevent the > scanner from working! It is when applications (such as SANE) send other SCSI commands to the luns > 0 that don't exist there could be problems. <snip/> Doug Gilbert
