Yet Another USB Memory Card Reader Thread

[funkyrat]

<Obligatory>I Love Knoppix! </Obligatory>

It appears that my Shuttle 6-in-1 memory card reader is being recognized and mounted properly, but I still can't get read it. I was hoping somebody could give me a clue.

Here's what I've done (most of this was culled from other threads here)...

(As root)

In the 'append' statement in /etc/lilo.conf I added "max_scsi_luns=6" and then executed /sbin/lilo

When I rebooted the following messages appeared in /var/log/dmesg

usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-ohci.c: USB OHCI at membase 0xe0c82000, IRQ 5
usb-ohci.c: usb-00:02.0, nVidia Corporation nForce2 USB Controller

usb.c: registered new driver usb-storage

...also

cat /proc/scsi/usb-storage-0/1 shows the following...

   Host scsi1: usb-storage
       Vendor:         Ltd
      Product: Winter Ver1.3

     Protocol: Transparent SCSI
    Transport: Bulk
         GUID: 07cc03200000104029804230
     Attached: Yes

I then made mount points underneath /mnt, called sda1-sda4

mount -t vfat /dev/sda1 /mnt/sda1 returns a "mount: /dev/sda1 is not a valid block device" error. the same error is returned for sda1-sda4.

mount -t usbfs /dev/sda1 /mnt/sda1 works!

However, here are the contents of /mnt/sda1...

001 and 002 are directories. 001 contains two binary files 001 and 002, while 002 contains binary file 001.

I've basically tried everything I know and am sort of at a brick wall in terms of my knowledge and understanding of linux devices. Any help would be greatly appreciated.

It seems that your card reader doesn't use the vfat filesystem. What is the specific model of your Shuttle 6-in-1 reader? You might also want to google the model name along with the keyword "filesystem".

Try mounting with msdos rather than vfat; ie. mount -t msdos /dev/sda1 /mnt/sda1

Unfortunately, I don't have your brand of card reader, so I am limited in my ability to help. It's entirely possible that your card reader may use a non-standard USB CompactFlash chip. See this project for an attempt to reverse engineer a linux driver for an non-standard USB chip: http://sourceforge.net/projects/usbat2

You might also want to check the search results for "Shuttle" on the Linux-USB Device Overview

Thanks for replying.

Actually, from the documentation it apparently supports both vfat and msdos. I did try mounting it as msdos as well and got the "not a block device" error as I did with vfat.

It's a Shuttle PC-12 6-in-1 card reader. See here.

From the Linux How-To that comes with it, it appears to be fairly standard. These are the kernel options it recommends:

The USB reader need following items:
 SCSI emulation support = y
 SCSI support = y
 SCSI disk support = y
 SCSI generic support = y
 Support for USB = m
 UHCI Alternate Drive(JE) or OHCI (Compaq,iMacs,OPTi,SiS,ALi,...) support = m
 USB Mass storage support = m
 Preliminary USB device filesystem = y
 Dos FAT fs support = y
 MSDOS fs support = y
 UMSDOS: Unix-like file system on top of standard MSDOS fs
 VFAT (Windows-95) fs support

The option items:
 USB verbose debug message = y
 USB Mass storage verbose debug =y

In terms of mounting it, their Linux How-To says that "mount /dev/sd? /mnt/sd?" should work (where ? is the device name/number). I tried that as well, of course, and still got the "not a block device" error.

Do you see anything non-standard about the kernel options it requires?
