I didn't realise you did see /dev/sda before. I didn't think MULTI_LUNs
would help due to that. If you did see /dev/sda before I would have
expected you to see the other devices. I am currently running the RH
2.4.20-20.7 (on a RH73 laptop) and therefore don't have MULTI_LUN support
enabled.

After plugging it in I have;

And pretty much the same;

As I don't have MULTI_LUN enabled I do;
bash-2.05a# echo >/proc/scsi/scsi "scsi add-single-device 1 0 0 1"
(I had ide-scsi loaded for CDRW use so this one is SCSI host 1 and not 0)
and then;
bash-2.05a# dmesg |tail -13

I don't have any media in the drive which is why it can't read the
partition table. I then repeat this for LUNs 2 and 3 and then
/proc/scsi/scsi has;
bash-2.05a# cat /proc/scsi/scsi

I don't have the message you saw;
> Sep 20 14:22:19 dino kernel: usb-uhci.c: interrupt, status 3, frame# 1071
but I think that is just a debugging message. Perhaps you somehow don't
really have SCSI_CONFIG_MULTI_LUN on?

Stephen.
