This is to help anyone trying to get their USB multicard reader working in

First, you must recompile the scsi module with "Probe all LUNs".
No you don't. It is a module option.

Also, don't forget to report your info upstream so that device can be whitelisted.

For some reason, I've never been able to get the 'options scsi_mod
max_scsi_luns=8' option to work. I get this message when I add it to
/etc/modprobe.conf:
scsi_mod: Unknown parameter `max_scsi_luns'
However, I've gotten good results from a three-line script that
coaxes Linux to recognize the additional LUNs on my Y-E media reader:
echo >/proc/scsi/scsi "scsi add-single-device 0 0 0 1"
echo >/proc/scsi/scsi "scsi add-single-device 0 0 0 2"
echo >/proc/scsi/scsi "scsi add-single-device 0 0 0 3"
Here's my /proc/scsi/scsi after running the script:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: Y-E DATA Model: CF Card Reader Rev: 1.03
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 00 Lun: 01
Vendor: Y-E DATA Model: SM Card Reader Rev: 1.03
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 00 Lun: 02
Vendor: Y-E DATA Model: MS Card Reader Rev: 1.03
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 00 Lun: 03
Vendor: Y-E DATA Model: SD Card Reader Rev: 1.03
Type: Direct-Access ANSI SCSI revision: 02
The '0 0 0' in each of the lines of my script stands for scsi0, channel 0,
ID 0. The last of the four numbers is the LUN number. I run my script
from /etc/rc.d/rc.local.

someone else has said that with the 2.6 kernel you should use "max_luns"
in /etc/modprobe.conf.
