Very Computer

i have red hat 9.0 kernel 2.4.20-6, an olympus d-230 (with a broken
usb out port), and an 4-in-1 usb media card reader (smartmedia is the
focus) plugged into a 4 port usb hub.

i am unable to mount the smartmedia card using mount -t vfat /dev/sda1
/mnt/camera. i have attemped this before and gooten no where. now i am
at the point where i need it working.

when i unplug the usb cable and then plug in the usb cable to my 4
port hub and then do dmesg, this is the output:

hub.c: new USB device 00:1f.2-2.2, assigned address 13
WARNING: USB Mass Storage data integrity not assured

SCSI error: host 0 id 0 lun 0 return code = 8000002
        Sense class 7, sense error 0, extended sense 0

sda : status = 1, message = 00, host = 0, driver = 08

 sda: I/O error: dev 08:00, sector 0
 I/O error: dev 08:00, sector 0
 unable to read partition table

if i attempt to mount it anyway, this is the output:

mount: No medium found

any advice or tips?

EXPN "smartmedia is the focus".  Remember that most X-in-1 USB media
readers don't work correctly unless you enable "probe all LUNs on each
SCSI device" in the kernel config.

It looks like your kernel's SCSI modules were compiled without "probe
all LUNs" support defined.  These X-in-1 readers are usually set up so
that one slot (the CF slot, usually) is the primary slot, so a Linux box
without probe-all-LUNs support will only see that slot.

Go to /usr/src/linux , make menuconfig (or make xconfig), SCSI Support,
set "Probe all LUNs" to Y.  Exit, saving changes, make modules
modules_install , then rmmod all your SCSI modules and modprobe them
back again.  Plug the device in, then look at the output from dmesg.
You should see 4 SCSI disks in the output and in /proc/scsi/scsi this
time.  Try mounting /dev/sdX1 (for X=a,b,c,d) and see which one works.
HTH,

thanks Dances with Crows. i'll try that and get back with you. i'm
hoping it's something simple like your suggestion. in order to mount
my parallel zip drive i have to "modprobe imm" first. i was wondering
if i had to do something similar with my smartmedia/4 port hub
to...and it looks like it.

ok, you were right. i don't have probe all luns configured in my
kernel (among others that i'd love to activate). i don't have the red
hat source code installed so i cannot do waht you suggest. i'm a noob
and i don't really want to dive into a kernel recompile. is there
another way that i can activate this?...possibly with a
/etc/modutils.conf file and an alias?

question: if i install the kernel source, which redhat 9 has 3 cd's,
how much hard drive space does that take? i only have 5 gigs free now.

No, the 3 source CD contain the source for the _entire distribution_,
not just the kernel. To recompile the kernel, use "Add/remove
applications" to install the kernel development packages.

ok, i was wrong. i did install the kernel source. in my redhat 9 i
have 2 folders called /usr/src/linux-2.4 and /usr/src/linux-2.4.20-6.
they both look the same to me. anyway, i tried setting the options in
kde's control center. after doing so it tells me to "make symlinks
dep", so i did that and it spat out a bunch of jibberish in my
terminal...so i thought it was working. i rebooting and still don't
see smartmedia card. i obviously did something wrong. when i go back
into kde's control center, i see that all my scsi options are still
checked.

linux-2.4 is a symbolic link to linux-2.4.20-6.

You didn't actually compile or install anything. Forget the KDE control
center, see the instructions how to do it properly:
