HOWTO: FC2 USB Multicard Reader

[Robert Dale]

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.
