trying to set up my USB 1.1 external one

[Albretch]

Hi *,

I am trying to use my external drive's USB port to connect (mount) using Knoppix

I think it is a USB 1.1 Wiebitech one with a Maxtor Drive inside.

But I can not. What are the steps you need to go to enable my external drive?

Here is some system info for you in case you need it to troubleshoot my problem

Thanks

I would get:

Verify that you have USB compiled into your kernel, that the USN core modules loaded and have the usbdevfs filesystem mounted

What version of Knoppix are you using? USB seems to be hit or miss depending on your version of Knoppix. See the bugs (http://www.knoppix.net/wiki/Bugs) page.

Well, I am using Knoppix version 3.9 and on the Bugs parade

http://www.knoppix.net/wiki/Bugs/3.9-2005-05-27

I don't see anything specific about problems trying to attach -USB external drives-, even though they talk about problems while booting from USB CD/DVD-ROMs and with USB pens, keys and flash drives

I am sure that people do things like that all the time to back up data. Or?

Thanks

I am sure that people do things like that all the time to back up data. Or?
I've noticed some speed issues with external USB devices. For example, I've attached an external USB2 drive and tried to copy data to it. I was getting write speeds of about 0.5 MB/s. When I attached the same drive via FireWire, I was able to get speeds of around 10+ MB/s. Since then I've stuck to FireWire. This was with Knoppix 3.8.2. So things may be different with other versions.

To troubleshoot your issue, boot into text mode with boot: knoppix 3 then run these commands:

lsmod > /tmp/lsmod.1
dmesg -c > /dev/null
Now plug in your external USB drive and run these commands:

lsmod > /tmp/lsmod.2
dmesg
diff -y /tmp/lsmod.?
Can you post the output from the last dmesg and diff commands?

> I've noticed some speed issues with external USB devices ...
A: Same thing with me. I wonder what the reason for this is?
I will le t you about K 3.9 after I test it

I did try to do things the exact way you told me but when I
tried to run X (startx) to be able to go online via a browser
and email you back, my computer froze.

Thanks for all the detail. But I only needed the ouput of the dmesg and the diff.


dmesg
Nothing? Interesting. That means that Knoppix isn't even seeing the device when it is plugged in.

Given the dmesg output, I'm not surpirsed that no new modules were loaded.


// __ But I still don't see anything in the drive even though when I take the drive out of the case and cable it in:

I could see all files without a problem

So if you hook up the drive via IDE cables, Knoppix recognizes the drive just fine and is able to mount the partition on it. But Knoppix does not recognize the drive via the USB. Right? If so, this narrows the problem down to the following areas:
- the drive enclosure
- the cable
- the USB card
- the driver for the USB card
- the driver for the USB drive

The first three are hardware issues, while the last two are software. How do you know that the enclosure, the cable, and the card work? This may sound like a silly question, but is the drive turned on when you plug the drive into the USB port?

As for the software drivers, try booting with boot: knoppix 3 and type the following commands:

rmmod ub
rmmod usb-storage
dmesg -c > /dev/null
modprobe usb-storage
lsmod > /tmp/lsmod.1

Now plug your drive in to the USB port and type these commands:

lsmod > /tmp/lsmod.2
( set -x
lspci
dmesg
diff /tmp/lsmod.?
) > /tmp/post.txt

Please post back the contents of /tmp/post.txt.

Where's your USB card? You should have an entry similar to this:

# lspci | grep -i usb

>Going back to my previous post: How do you know that the enclosure, the cable, and the card work?

I have the same problem.

Knoppix DVD 4.0 ran fine, and recognized a FAT pendrive.

Then I tried adding an external Maxtor USB formatted with 3 Linux partitons and one big FAT partition made with Partition Magic.
I tried the pivot_root install.
That worked (except I can't get out of Nautilus to KWindows <can now>, and Gnome gives me a "Knoppix unreachable" error.)
Firefox and Thunderbird both work running from the DVD and using pivot_root.

The FAT pendrive works fine in both configurations. <no it doesn't, only from DVD, not pivot_root drive> I do have myconfig and PH on the pendrive...

But the external USB drive <fat partition> doesn't. The error is "mount: mount point /mnt/uba1 does not exist" (It shows a pendrive icon in Konqueror; and QTParted shows 9 partitions, of which 5-9 are the ones I want to access)

<Actually, uba5 and uba6 (linux partitions) do mount, but using pivot_root, ubb1 and uba9 (FAT partitions) don't (mount wrong FS type)

The external drive works fine when I boot to WindowsXP, so enclosure, cable, and card are fine.

<AND everything works fine with Kanotix...>

[rwcitek]

But the external USB drive <fat partition> doesn't. The error is "mount: mount point /mnt/uba1 does not exist"
Boot knoppix without the USB drive attached. Then type this in a root terminal window:

dmesg -c > /dev/null
Attach your USB drive and type the following code:

( set -x
uname -va
cat /etc/knoppix-version
lspci
dmesg
cat /proc/partitions
) >& post.txt

Please post the output of post.txt

Can't do this. Don't know enought about Linux.

Did it once when I switched to 'shell 2 ?' as root, but couldn't copy the post.txt to ubb1 (not writeable)
When I switched to shell 5 (the GUI), in which I know how to make ubb1 writeable, couldn't find post.txt from shell 2.
Tried again in GUI shell console; dmesg -c > /dev/null 'Operation not permitted'; tried again with su, but don't know enough to make that work.

Best I can tell uname -va produced Linux Knoppix 2.6.11 #2 SMP
lspci produced two USB controllers and a hub.
cat /proc/partitions showed ubb1 (the pendrive), and ubba (the external Maxtor) 5,6,7 (linux partitions)
but NOT the one I really need, uba9, the large FAT32 partition.
dmesg is 14k (I assume your first instruction would clear that, but I can't make it work).
I do see one line "FAT: invalid media value (0xb9); VFS: Can't find a valid FAT filesystem on dev hda"
That's the NTFS windows "C:\" drive; I can read from it fine.

And in my first try with Kanotix, everything appears to be working fine (uba9 is accessible)
<well, not everything. I can't figure out how to load myconfig...and the two USB devices, while accessible, seem to switch places after a reboot.>

Knoppix sees most but not all of your partitions. I'm wondering if this is a limitation of the USB driver trying to act like a SCSI device. IIRC, SCSI drives can have only 8 partitions. If that hold true for USB also, then you would not have any partitions 8 or higher. I hope I'm mistaken. I'll play around with my USB and FW drives to see if I can partition my drives similar to the way you have yours.

In the mean time, have a look at the partition table of uba:

fdisk -l /dev/uba
Does that list all the partitions?


It's ubb9 (the big FAT partition) that I need to get at.
I've found problems with Kanotix, too, but it mounts that partition just fine.
What happens if you try to mount it manually? That is:

mkdir /mnt/uba9
mount /dev/uba9 /mnt/uba9
ls -la /mnt/uba9
df -HT /mnt/uba9

Well, I'm the one who's asking for help...


fdisk -l /dev/uba

Does that list all the partitions?

Yes, it does. So does QParted, and they show up when I boot with Kanotix.

Code:
mkdir /mnt/uba9
mount /dev/uba9 /mnt/uba9

after mount /dev/uba9 /mnt/uba9 I get "special device /dev/uba9 does not exist"

I've tried disconnecting the USB devices one at a time; no change.
Knoppix just doesn't like that big FAT partition (although Kanotix has no trouble with it)

[Albretch]

So you are saying that kanotix

http://distrowatch.com/table.php?distribution=kanotix

had no issues handling FAT FAT32 partitions from external USB drives?

THis is my problem too

I wasn't able to solve my problems. I had a technician tell me that I had to plug the USB drive before knoppix boots, which made me wonder what was the idea then of using a USB device.

Let me try kanotix then

I have noticed lots of problems with USB/Firewire devices with my knoppix distro 3.9

I am still wondering if there is anyone outthere using knoppix with external devices.

[Zoltan]

So you are saying that kanotix

http://distrowatch.com/table.php?distribution=kanotix

That's right, athough I've had problems with Kanotix saving a configuration.

I have two USB devices attached to a laptop during boot, a FAT16 pendrive and an external 250GB Maxtor.

The external Maxtor wound up with 8 partitions, although I only created 4 Linux partitions and one FAT32 partition.

Both are recognized by both Knoppix and Kanotix. The FAT32 partition on the Maxtor is recognized by Knoppix (QParted shows all of them), but I can't seem to get it mounted.

Kanotix mounted all of them.

I'm looking at /dev and /etc/fstab to try to figure out the difference; but I need to spend some time on a linux book first.

What I'm trying to do is create an external drive that will RUN Linux (probably has to initially BOOT from a CD/DVD) without wrting anything to the Windows C:\ drive.

[Albretch]

Actually I have a Maxtor Drive too (a MAXTOR 6L080J4, ATA one) inside a wiebetech enclosure with 2 Firewire connectors and one USB one.

After burning a kanotix copy (I liked it already, for some reason it is faster than Knoppix!! (and I don't think that the reason is that the default lang of most applications is German :?, which by the way I speak))

I got some info from

http://wiki.kanotix.net/CoMa.php?CoMa=usb-storage

but it appears to be for digital cameras only?

I see the LED on the drive reacting and running /etc/hotplug/usb/usb-storage, shows me

Could you tell me exactly how is it you mounted you external ATA drive using kanotix?

I plugged it in.

Actually, it's plugged in when I boot.

In my case, both Knoppix and Kanotix recognized the USB device(s). On one laptop, I have two Maxtors (One-Touch), on the other, a Maxtor and a pendrive.

My problem is that Knoppix doesn't recognize the FAT partition on one of the Maxtors, while Kanotix does.
Both Knoppix and Kanotix recognize the single NTFS partition on the C:\ drives and the Linux partitions. Both recognize the single FAT16 partition on the Pendrive. Robert has speculated that I may have too many partitions on the drive Knoppix won't read, and I'm beginning to think he may be right. I tried deleting one with QTParted, but it wouldn't let me. I'll probably try deleting one in Windows eventually.

But at the moment I'm working my way through O'Reilly's "Running Linux"; there's too much I don't understand yet.[/quote]

What is then the fun of having a hotpluggable drive when you must have it plugged when you boot?

I downloaded the Knoppix 4.01 DVD image.

At first impression, everything now seems to work, including that elusive FAT32 partition on the external USB drive.

...and FWIW, I plugged in a pendrive to the running system, and it was recognized.

Now I've got to get it to recognize the USB CDROM as well.
Actually, it does, but both CDRom entries refer to the same CDRom.
