Well, I guess I must, partially, take back what I said about the
SanDisk 6 in 1 card reader not working with linux.
In response to my previous posting, I was advised to RTFM (actually,
the USB FAQ). The FAQ question about multi-purpose storage devices
was the key to making my system recognize the different slots of the
SanDisk reader.
I still cannot mount my SM card, which is plugged into the SanDisk, as
a file system. But, I am able to read the card using mtools!
The following information relates to my attempt to mount the device.
I would appreciate any advice on how to overcome this problem.
If you don't care about my problems and just want to see how I used
mtools to read from the SanDisk device, skip down to the
"------------" line.
Here's what my /proc/scsi/scsi looks like:
[swing dadamia]$ cat /proc/scsi/scsi
Attached devices:

When I plug the SanDisk device into my USB hub (with my SM memory card
already in it), here's what I see in my /var/log/messages file:
Dec 7 17:56:55 swing kernel: hub.c: USB new device connect on bus2/2/1,
assigned device number 7
Dec 7 17:56:58 swing kernel: usb_control/bulk_msg: timeout
Dec 7 17:56:58 swing kernel: usb.c: error getting string descriptor 0
(error=-110)
Dec 7 17:57:00 swing /etc/hotplug/usb.agent: Setup usb-storage for USB
product 781/621/5
Dec 7 17:57:00 swing /etc/hotplug/usb.agent: missing kernel or user mode
driver usb-storage
Why am I seeing that last line? According to lsmod, usb-storage is
loaded?
When I try to mount, I get:
[swing dadamia]# mount -t vfat /dev/sdc /mnt/sandisk
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
or too many mounted file systems
[swing dadamia]#
And, the following appears in /var/log/messages:
Dec 7 18:00:29 swing kernel: FAT: bogus logical sector size 0
Dec 7 18:00:29 swing kernel: VFS: Can't find a valid FAT filesystem on
dev 08:20.
I know that /dev/sdc is the right device, because all the other
choices (sda, sdb, and sdd) report "No medium found". Also, "tar -rf
/dev/sdc" makes the correct LED blink on the SanDisk unit.
The SmartMedia card I am using is from an Olympus D-520 digital camera.
Anyone have any more ideas?
-----------------------------------------------------------
Here's how I am using mtools to read the SanDisk.
First, make a file in your home directory called .mtoolsrc like the
following:
[swing dadamia]$ cat .mtoolsrc
drive s:
file="/dev/sdc"
partition=1
mtools_skip_check=1
[swing dadamia]$
You can use a different drive letter, if you want. Also, the "sdc"
applies to the slot that the SM card goes into. If you are using a
different slot, you'll need a different device (sda, sdb, sdc, or
sdd). Now, you can use mdir, mcopy, etc. to talk to the SanDisk.
Examples:
[swing dadamia]$ mdir s:
Volume in drive S has no label
Directory for S:/
DCIM <DIR> 12-07-2002 21:03
1 file 0 bytes
13 746 176 bytes free
[swing dadamia]$ mdir s:DCIM

[swing dadamia]$ mdir s:DCIM/100OLYMP
