    This is to help anyone trying to get their USB multicard reader working
    in Fedora Core 2.

    First, you must recompile the scsi module with "Probe all LUNs".
    su root; cd /usr/src/linux-<version>;
    I use "make menuconfig" -> Device Drivers -> SCSI device ->
    check "Probe all LUNs on each SCSI device". Exit and save.

    FC2 adds "custom" to the version in the kernel source. So you can do
    one of two things:

    1) Simple but long: Recompile kernel and modules, install. Update grub.
       Reboot.

    2) More complex but faster: Edit Makefile and remove "custom" from EXTRAVERSION. make modules. Kill (ctrl-c) it after you see scsi_mod.ko built.
    copy the new drives/scsi/scsi_mod.ko over the old /lib/modules/<version>/kernel/drivers/scsi/scsi_mod.ko.
    reload the new scsi_mod module.

    Now you're ready to read cards!

    I had to reload the usb_storage module every time i added or removed a card
    - rmmod usb_storage; modprobe usb_storage;

    YMMV.

    Let me know if there's an easier way to tell the usb-storage module
    that a card has been added or removed.
