Is this a reader that will take more than one type of media?

I have an Addonics reader that takes 4 different types of media and in order 
to get them all working I run the following script:

#!/bin/sh
echo "scsi add-single-device 2 0 0 0" > /proc/scsi/scsi
echo "scsi add-single-device 2 0 0 1" > /proc/scsi/scsi
echo "scsi add-single-device 2 0 0 2" > /proc/scsi/scsi
echo "scsi add-single-device 2 0 0 3" > /proc/scsi/scsi
cat /proc/scsi/scsi

You would have to change it to match your situation but essentially it is 
adding devices at LUNs  0,1,2, and 3.      I believe all you would have to 
change is the '2' to be a '0' since yours is on SCSI ctlr 0  and mine is on a 
machine that already has SCSI ctlr 0 and 1 for real and 2 as the virtual 
scsi.

The last line of the script should show you all 4 (or whatever you have) 
devices with their media types (CF, MMC, etc.)
