my Lexar device is detected by the kernel, and quite a bit seems to be working ok, i just can see my pictures.... Any help is greatly appreciated.

Here are the gory details:

Please Help!

You should have scsi and scsi-disk enabled in the kernel. I think the scsi-disk module is sd_mod. I have a ScanDisk 6 in 1 card reader. If I install a compact flash card I mount it like this:
mount /dev/sda1 /cf1
If I install a SD card I mount it like this:
mount /dev/sdb1 /sd1
I haven't tried the other media types but I think they would be sdc1 ...

My cat /proc/bus/usb/devices looks similar to yours.
I would suggest you make sure you have scsi-disk enabled. Try this:
dmesg | grep sd
SCSI device sda: 1000944 512-byte hdwr sectors (512 MB)
sda: assuming Write Enabled
sda: assuming drive cache: write through

Attached scsi removable disk sdc at scsi0, channel 0, id 0, lun 2
Attached scsi removable disk sdd at scsi0, channel 0, id 0, lun 3

The above is with only the compact flash installed.

i loaded sd_mod which seems also to load scsi_mod:

But Still no dice.... Here is dmesg | grep sd

which seems to show some error at least...
Does that give anyone any ideas? It does not help me....
Thanks for the speedy replay /bin/bash

Sorry I can't be of more help but it looks like you have all the modules you need to get it working.

Things I would try...
Try a different USB port.
If available try a different card.
If available try a different card reader.
Try booting with card installed and add sd_mod to your /etc/modules file.

If all that fails I would suggest a newer kernel. Kernel-2.4.20 is quite old and all the hotplug "back porting" may have missed that kernel, plus there have been major updates/improvements to USB since that kernel.

did get this sorted? - i have exactly the same problem with a secure digital card - the dmesg reports errors. I have no problems with a smart media card.

Thanks for any help

The problem most likely is because your kernel doesn't support multi-lun scsi devices. I had the same problem with my Mandy 9.1 initially. Unless you know how to enable this option without recompiling your kernel, then it's recompilation time Basically, your card reader presents to the scsi subsystem as a single device with multiple LUNs. If your kernel doesn't accept multiple lun devices, then it'll only see the first device (which is often the CF part of the device). All is fine and dandy unless you want to use one of the other media types.

Hope this helps.

thanks grant - i've got a copy of mandy 9.2 - looks like time to upgrade - here goes.. i'll report back in a week no doubt - when i've finished hacking my machine to pieces.

Mandy 9.2 should have Mutli LUN enabled. Can't remember for certain (it's been a while since I booted into 9.2).

Try adding this to your 'append' statement in lilo (or the equivalent in grub):

append="max_scsi_luns=6"

This is late as far as a reply but did you get this working?

I just did a few minutes ago so if you are interested I can post my process.

Its never too late to post an answer to a problem. Someone may benefit.

my fix was to install xandros - sorry to be a whimp. xandros also loves winmodems - no additional software required!! thanks, duncan

OK, This took me a while to figure out and compile into directions so here goes. Hope someone benefits from it.

To start:

My system is:

Starting kernel revision 2.4.21
Red Hat Enterprise Linux ES release 3 (Taroon Update 4)

My problem was to get a Lexar Card Reader which is USB2 compatible to mount.

Based on the several posts I read, I ended up editing and recompiling the kernel to solve the problem.

Make a copy of your starting kernel source code usually located under /usr/src/linux-something

1) Edit the lines in drivers/scsi/scsi_scan.c involving max_scsi_luns to allow more than 1. I changed both ( and could have just removed the if statement ) just to ensure the value was taken at 6. Alternatively, should you know how to initialize the value externally, which I could not figure out, you can set MAX_SCSI_LUNS. My reader has 3 slots so technically it could have been set lower.

#define MAX_SCSI_LUNS 0xFFFFFFFF

#ifdef CONFIG_SCSI_MULTI_LUN
/*
*static unsigned int max_scsi_luns = MAX_SCSI_LUNS;
*/
static unsigned int max_scsi_luns = 6;
#else
/*
*static unsigned int max_scsi_luns = 1;
*/
static unsigned int max_scsi_luns = 6;
#endif

2) Prepare to make the kernel.

# make distclean
# make mrproper
# make config

(I had many problems with just running make xconfig as others claim but this process seemed to work every time even though many questions were somewhat painful. Additionally, the resulting .config file was actually different which makes me wonder what xconfig does different from config other than the pretty gui)

During this I changed 1 and only one answer:

*
* Some SCSI devices (e.g. CD jukebox) support multiple LUNs
*
Enable extra checks in new queueing code (CONFIG_SCSI_DEBUG_QUEUES) [N/y/?]
Probe all LUNs on each SCSI device (CONFIG_SCSI_MULTI_LUN) [N/y/?] (change to y)

Now, edit the first couple of lines of the Makefile to give a unique version to the kernel. Typically the SUBLEVEL and EXTRAVERSION are changed here.

Ex.
VERSION = 2
PATCHLEVEL = 4
SUBLEVEL = 22
EXTRAVERSION = -JS

creates a revision of 2.4.22-JS

3) Make the kernel (using the revision info above)

# make dep
# make
# make bzImage
# make modules
# make modules_install
# /sbin/mkinitrd /boot/initrd-2.4.22-JS.img 2.4.22-JS
# cp vmlinux /boot/vmlinux-2.4.22-JS
# cp System.map /boot/System.map-2.4.22-JS
# cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.22-JS

4) Prepare for booting the new kernel

# cd /boot

Remove the old link from System.map to your old map and create a new one.

# ln -s System.map-2.4.22-JS System.map

Add entry to /boot/grub/menu.lst for your new kernel

title Red Hat Enterprise Linux ES (2.4.22-JS)
root (hd0,0)
kernel /vmlinuz-2.4.22-JS ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.22-JS.img

5) Reboot

6) If all went well then the Card Reader should be completely visable to the system.

The card reader I have has 3 ports for SanDisk, SmartMedia, and CompactFlash, Therefore,

# mkdir /mnt/cf /mnt/sd /mount/sm
# chmod 700 /mnt/cf /mnt/sd /mount/sm

Another post recommended the chmod because then you can't access the /mnt/sd, or other directories unless they are mounted. This may be confusing but when it comes to mounting, it's newbie friendly.

Now we need to update our /etc/fstab file. You can use any text editor, as long as you are still root. Add lines to the end of the file as needed: (note: it has been mentioned by others that the fstype field can be vfat for these but I have had issues with that working. auto works for mine. If yours does not, try vfat.)

/dev/sda1 /mnt/sm auto users,owner,noauto 0 0
/dev/sdb1 /mnt/cf auto users,owner,noauto 0 0
/dev/sdc1 /mnt/sd auto users,owner,noauto 0 0

With this in place, as root you can mount each using:

# mount /mnt/sd (or which ever of the three you want)

7)You should now see the structure under that link

# ls /mnt/sd
dcim misc

8) Have fun with your pictures.

Sometimes it will help to format the card again. if it's not the afore mentioned reader device problems
