Multi Card Reader (usb mass storage)

Shak · 12-31-2002, 10:40 AM

Hiyas,

Yeeps, this seems to be a problem and a half, I wonder if anyone on here can help me!

Right, heres the scenario: I have a USB card reader that reads 6 types of cards (CF/SD etc). It works in Windows, but I need to use it in Linux - because of PsiLinux.

I added the modules I thought I was going to need: (Im running a default redhat kernel as I havent got round to recompiling yet :P)

Code:

[root@ernie usbmgr]# /sbin/lsmod
Module                  Size  Used by    Not tainted

jbd                    56688   3  [ext3]

Right, looks all well and good to me. When I plug the device in I get:

Code:

Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices
  Vendor: Generic   Model: USB Storage-SMC   Rev: 0207
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 8
USB Mass Storage support registered.

Showing in dmesg and /var/log/messages. I thne used a tool called SCSI enquiry to see which device it was:

Code:

[root@ernie sg_utils-1.02]# ./scsi_inquiry /dev/sda
    Generic   USB Storage-SMC   0207, byte_7=0x0

And checked in /proc/scsi/scsi:

Code:

[root@ernie sg_utils-1.02]# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: Generic  Model: USB Storage-SMC  Rev: 0207
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: LITE-ON  Model: LTR-32123S       Rev: XS0F
  Type:   CD-ROM                           ANSI SCSI revision: 02

Therefore it looks like I have a system that should mount the disk.

Code:

[root@ernie sg_utils-1.02]# mount /dev/sda /mnt/floppy
/dev/sda: Input/output error
mount: you must specify the filesystem type

Attempt 1: Note its the /dev/sda not any partition, also note that there's an input output error specified.

I then tried with vfat specified, this doesnt seem to work either:

Code:

[root@ernie sg_utils-1.02]# mount /dev/sda /mnt/floppy -t vfat
mount: wrong fs type, bad option, bad superblock on /dev/sda,
       or too many mounted file systems

This time theres no input/output error... so I checked /var/log/messages again to see

Code:

Dec 31 16:20:23 ernie kernel: Device not ready.  Make sure there is a disc in the drive.
Dec 31 16:20:23 ernie kernel: Device 08:00 not ready.

Dec 31 16:20:23 ernie kernel: FAT: unable to read boot sector
Dec 31 16:20:23 ernie kernel: Device not ready.  Make sure there is a disc in the drive.

It doesnt think theres a disk in it!

And also there seems to be a huge problem with detecting its size, do you reckon this just isn't compatible with Linux?

The model number on it says:

Code:

CR-V10-U6

I googled for it, and I cant find much support anywhere!

Anyone got any ideas?

Try /dev/sda1

Shak · 01-02-2003, 12:50 PM

Ive tried it, its says its not a valid block device.

Shak

finegan · 01-02-2003, 02:18 PM

Its locating the device, its just not registering a media presence, that's the exact same read I get from a zip drive with no disk in it. Maybe there are 2 actual device readers in there and its too stupid to work unless the first one has something in it... or somesuch. What do you have in there now? Also, what kernel? 2.4.18 if its base RH I'de wager. A lot of usb device upgrades have made it in since 18.

Cheers,

Finegan

Im going to try with .20 and upgrade my kernel, Im just lazy and havent rolled my own, also a mate pointed out that I may need:

CONFIG_SCSI_MULTI_LUN enabled and I dont as that allows multi devs. Between us I think we have deduced that the hardware inside should be 4 different SCSI devs, but is only one.

see next message...

Srikanth W · 01-13-2003, 05:17 AM

Add this line
/dev/sda /mnt/floppy vfat noauto,user 0 0
to your
/etc/fstab

and try
mount /mnt/floppy

Cheers,
Srikanth.

Srikanth W · 01-13-2003, 06:09 AM

add
/dev/sda /mnt/floppy vfat noauto,user 0 0
to
/etc/fstab
do
mount /mnt/floppy

I have the exact same problem with a 6 in 1 reader, dmesg reports there is no disc in the drive, and fdisk cannot find a partition table for /dev/sda
the deal has 4 places to plug in memory cards, the only ones i have tried are a sony memory stick in the 2nd port and a sd card in the 3rd port, same problem for both, same results if there are no memory cards in the thing.

jomoby · 02-26-2003, 01:02 PM

youre mate was right Shake
i just tried compiling 2.4.20 with
CONFIG_SCSI_MULTI_LUN=y
and it works!!
it takes up the first 4 scsi devices

my sony memory stick is on sdd

bash-2.05# fdisk -l /dev/sdd

Disk /dev/sdd: 16 heads, 16 sectors, 991 cylinders
Units = cylinders of 256 * 512 bytes

Device Boot Start End Blocks Id System
/dev/sdd1 * 1 990 126703+ 6 FAT16

Hi,

I have the same problem, using a MBO-CardReader.
The Probleme exists after starting of KDE2. Before starting the device works perfectly, but if I started KDE2 the Reader says "no media found" and gives also the following message - according with the first message on top of this page:

# mount /dev/sda1 /mnt
sda: READ CAPACITY failed.
sda : status = 0, message = 00, host = 7, driver = 00
sda : sense not available
sda : block size assumed to be 512 bytes, disk size 1GB.
sda: I/O error: dev 08:00, sector 0
I/O error: dev 08:00, sector 0
unable to read partition table
mount: no media found

Unfortunately due to time constraints I still haven't got round to this :X But when I get it fixed Ill write a HOWTO for it
