How to get access to an USB storage device?

If all goes well, you plug in the device and Knoppix recognizes it as /dev/uba or similar. I've had the best luck by plugging in the USB device and then booting Knoppix.

Try that and let us know how things go.

I do not have /dev/uba on my system.
There is /dev/usb directory with many files like dab..., dc..., ez..., lp..., mdc..., mouse..., rio..., scanner..., tty...
I do not know if any is suitable for my device.

Hmm. Sounds like your USB storage device is not being recognized. Boot up again with the USB device plugged in and type these commands:

cat /proc/partitions
lsmod | grep usb
lspci
lsusb
dmesg | grep -A 3 -i usb
Please post the results.

In Konqueror, press F9 to open up the side-bar if your USB device is recognized it should look like this:

+ Hard Disk (sda1) [/mnt/sda1]

Looks like you're missing a few modules. Here's what mine looks like:

lsmod | grep -i usb
usbhid 42176 0
usb_storage 63296 0
usbcore 101496 7 usbhid,usb_storage,ub,ohci_hcd,uhci_hcd,ehci_hcd

Looks like it found it but didn't recognize it as a storage devices.

Try booting up. Open up a terminal and type these commands:

sudo su - # become root
modprobe usb_storage
modprobe ehci_hcd
lsmod | grep usb
cat /proc/partitions

Please post the output of those commands here.

Hello Robert,
Hereafter the results of the tests.
Knoppix sees it but still doesn't want to recognize it as a storage device.

Let's try something else. Boot into Knoppix without having the storage device attached. Then type the following:

cat /etc/knoppix-version
uname -va
lsusb
sudo dmesg -c >> dmesg.txt
echo '===' >> dmesg.txt
Now attach the storage device to the USB slot of your computer and type the following:

lsusb
sudo dmesg -c >> dmesg.txt
grep -B 3 -A 1000 '^===' dmesg.txt
Please post the output of those commands here.

Hello Robert,
Please find hereafter the results of the tests.
I feel a scsi module is missing but wich one?
Ubuntu Live recognizes my device.
It includes a module scsi_mod that is used by usb_storage.
But modprobe can not not find scsi_mod on my Knoppix.
I think Ubuntu is based on an older kernel.

As far as I can tell, Linux sees your USB storage device as /dev/uba. Try these commands as root:

cat /dev/uba | od -bc | head
fdisk -l /dev/uba
Please post the results.

My suspicions are that even though the kernel recognizes your USB device, the ub driver may not be working correctly with it.

You are right.

From another list someone recommend that the ub driver be removed and use usb-storage instead. So, try this:

sudo su - # become root
rmmod ub
modprobe usb-storage
At this point, it can't hurt, right? ;)

Try loading the imm and/or ppa module.

[jjbergdolt]

sudo su - # become root
rmmod ub
modprobe usb-storage
-----
I do not see any changes.
Is a scsi support required for usb storage devices?
lsmod does not display any scsi module.

[jjbergdolt]

Try loading the imm and/or ppa module.
---------
modprobe imm
FATAL: Error inserting imm (/lib/modules/2.6.11/kernel/drivers/scsi/imm.ko): Unknown symbol in module, or unknown parameter (see dmesg)

When I compare with Ubuntu live that is also based on Debian, I notice the following:

scsi-mod is not included in Knoppix.
When I try to load it I get an error message, module not found.
------
uname:
Linux ubuntu 2.6.10-5-386 #1 Tue Apr 5 12:12:40 UTC 2005 i686 GNU/Linux

This is an older kernel version, Knoppix is 2.6.11

[jjbergdolt]

After loading a module with modprobe is it possible to force Knoppix to redetect again all devices?
Is it done automatically?

[rrfish72]

Use modconf as root to load all modules that you want to load automatically. Just enter through until it says successfully loaded. Type modconf in a terminal and goto scsi to find the modules mentioned.
