Multicard_reader

Basic Setup

Kernel Setup

First you need a basic USB setup, see this guide. Then you may need also:

 Device Drivers  --->
     SCSI device support  --->
          <*> SCSI device support
           [*]   Probe all LUNs on each SCSI device
 

Without it, only one slot of your device will work properly, because the system will stop looking for disk after it finds the first one. With this option it will keep looking for other disks until it probes all possible addresses. (There are also some new Multicard reader that does not need this option).

Software Setup

To tell the driver, how many devices he should expect (XY is here the number; replace it with the number of your card slots), you have to:

• If you build the SCSI device support driver into the kernel, append scsi_mod.max_scsi_luns=XY to the kernel line of your boot manger config, e.g. /boot/grub/grub.conf:

 kernel other_kernel_options scsi_mod.max_scsi_luns=XY
 

• If you build the SCSI device support driver as modules, add the following to /etc/modprobe.d/scsi_mod:

 options scsi_mod max_scsi_luns=XY
 

Afterwards run update-modules.

To mount now a card, see this guide.
