I am trying to get my SanDisk 2in1 card reader to work. From what I understand the Smartmedia slot ( the one I need) is on LUN 1. Is there a way to enable that additional LUN? I have asked on the Knoppiz mailing list if "Probe Additional LUNs" was selected in the latest versions kernel but got no reply. Any help would be appreciated.
For sure you can do it by selecting "probe multiple LUN's on each device" when configureing a custom kernel. I have also heard of people using various boot params, but I've not had any success that way.
You could try something like this for example:
echo "scsi-add-single-device 1 0 0 1" >
/proc/scsi/scsi
That might get your card reader into the /proc filesystem.
BTW-
Have a look at /usr/src/linux/.config and you'll see this:
VeeDubb is right- you'd need to recompile the kernel. I don't know why it's not set.Code:CONFIG_SCSI_MULTI_LUN is not set
According to Klaus, on the mailing list, it's not set because then there would be 7 erroneous SCSI drives on the desktop.Quote:

I have not tried it with Knoppix, but it has worked with both RedHat 9 and Mandrake 9.1
in /etc/modules.conf add the line
options scsi_mod max_scsi_luns=12
The only way I know of doing this with Knoppix is with a remaster.
I forgot that /etc/modules.conf is not to be edited. It is built by the stuff in /etc/modutils
I would add it to the end of /etc/modutils/aliases
# support for SansDisk 5-in-1 reader
options scsi_mod max_scsi_luns=12
And then run update-modules as root for the changes to take effect on the next reload of the module.Quote:

cat /proc/scsi/scsi
So far, it looks just as before.Code:Attached devices:

But:
scsi_info /dev/sdc
That last thing wasn't there before your hint. But still I cannot mount the MMC card:Code:SCSI_ID="0,0,2"
MODEL="IC USB Storage-MMC"
FW_REV="301b"
Code:mount /dev/sdc1 /mnt/test
mount: /dev/sdc1 is not a valid block device
I would try
The reason being, is I suspect the following is true:Code:mount /dev/sdc3 /mnt/test
Quote:
/dev/sdc1 CFC
/dev/sdc2 SMC
/dev/sdc3 MMC
/dev/sdc4 MSC
unfortunately no:
CFC *does work* with mount /dev/sda1 /mnt/test
yet I don't know how the others (especially the MMC) can be mounted... but I think it is sdc1 because of
scsi_info /dev/sdc
Interestingly,Code:scsi_info /dev/sdc
SCSI_ID="0,0,2"
MODEL="IC USB Storage-MMC"
FW_REV="301b"
cdrecord -scanbus
How can I make MMC show up here instead of CFC?Code:Cdrecord 2.01a14 (i686-pc-linux-gnu) Copyright (C) 1995-2003 Jörg Schilling

I've just written a post about how to detect and mount a 6-in-1 USB multi-card reader (for Compactflash, Smartmedia / x-Media, SD/MMC and Sony Memorystick), without recompiling the kernel, at this thread in the Tips & Tricks forum .
