USB not working

[britt]

Hi all,

I hope someone here can help me with my USB problem, I spend already hours on this, googling for usb and linux, but haven't found a working solution so far:
I don`t get my USB devices to work. They seem not to be recognized by Knoppix, though kernel modules are loaded:
lsmod:
:
usbserial 19676 0 [visor]
usb-storage 62016 0 (unused)
usb-uhci 21836 0 (unused)
usbcore 57824 1 [visor usbserial usb-storage usb-uhci]


Am I right that usb devices (usb stick or Palm) should be mounted automatically by the system? Or do I have to mount them manually? I tried (without success): mount -t vfat /dev/sda1 /mnt/usbdevfs or mount /proc/bus/usb/ /dev/usbdevfs.

My system is: HP Omnibook 4150 with USB 1.0, Knoppix 3.7 (HD installed) with Kernel 2.4.27

Any help is appreciated!
Best regards
britt

[OErjan]

first, what type of hdd install? secondly what does

dmesg|grep ub&&dmesg|grep sd give you?
what does
uname -a

lspci

cat /etc/fstab

fdisk -l
have to say?
whit these things we have a better chance of helping you.

Hi OErjan,

thanks for your answer! Below the the info you asked for. That was a good idea: dmsg issues a remount parameter error. Maybe this is the problem. Do you know how to fix it?

best regards
britt

[Tom2000]

I have the same problem, except using a Toshiba P25-S520 laptop and a Sandisk Cruzer Mini 512 MB flash drive, booting from the Knoppix 3.7 CD.

The flash drive isn't recognized either by hotplugging it or by inserting it into a USB port prior to a cold boot. The drive works fine in WinXP Home, SP2. I have the same problem when I insert the flash drive into any of my four USB ports.

"mount -t vfat /dev/sda1 /mnt/sda1" results in a message that says something like "/dev/sda1 isn't a block device."

I noticed that the following line appears in the startup message whether or not I have the flash drive installed when I boot - something like:


USB ports found, managed by hotplug: sync:[001 001 001 001 ]

Also, there is mention of hda and hdc initialization, but nothing about sda when I'm booting with the flash drive plugged in.

I would sure appreciate it if you could help me sort this out. I’d really like to be able to use my flash drive with Knoppix.

Many thanks,

Tom
Seattle


Note: the following snapshots were taken after a boot with the flash drive plugged in.

hmm i see no weird stuff ecept that sysfs bit.
have you tried kernel2.6 (it is on the cd)
actually it seems you both have mised about 2/3 of the info in dmesg i wanted.
issue this as ONE comand ALL of it(copy paste?), then it would be nice to see the whole output..

dmesg|grep ub&&dmesg|grep sd&&dmesg|grep usb
then i still want to know what version of hdd-installl you have. beginner? debian-style?...

[Tom2000]

OErjan,

Thanks very much.

I got tired of loading Knoppix to the ramdisk so I could burn a CD just to transfer the command output back to Win. Overkill. Today's project was re-sizing my NTFS partition, then creating a shared FAT32 partition (and a few Linux EXT3 and SWAP partitions while I was at it.)

I ran out of time today, so I'll continue testing tomorrow and post the results.

Again, many thanks.

Tom

Hi OErjan,

thanks for your answer. Here is the output of dmesg you wanted:

What do you think of the"remount parameter error" that dmsg issued (see my last mail)?

Best regards

[britt]

Hi OErjan,

in addition to my last mail: I have tried kernel 2.6, which does not work either :-(

regards
britt

[app]

I have basically the same problem, with laptop Fujitsu Amilo Pro V2000. Tried with 3.7, both kernel version.

[OErjan]

hmmm. how does it work if you insert the stick AFTER you have booted?
i use same brand of usbstick (128mb) antd that works.

eh, ok, do you have anything important on that stick?
if not you might try to format it under windows as fat32 (iirc i did that sometime) and retry in linux.

as to palm you use kpilot for that.
hmm, after boot insert your palm hotsync cable.
Push the hotsync button, then
tail /var/log/syslog/syslog this will, hopefully, show what your palm is atached as, usually something like /dev/ttyUSB1.
then go trough the kpilot setup and use that /dev/XXXXusbY as your device.
I have not much experience with palm usb in linux, I use a serial conection to my palm.
there is a program it alows me to use the palm as a serial dumb terminal for linux (tiny text, and using the pen for input is a pain, but it is ok for weiving logs on the server...)
here you have some more on palm and knoppix
http://www.knoppix.net/forum/viewtopic.php?t=9387

[britt]

Hi OErjan,

thanks for the palm hint, i'll try that out and post result.

concerning the usb stick: i always inserted it after boot, with no success.

concerning "tail /var/log/syslog/syslog": this does not exist on my computer. i was looking for these outputs and wondering where they go? there is a file /var/log/syslog but it is empty (0 byte size). unfortunately i don't know which installation i chose, it was not beginner, i think it was debian style but i am not shure (is there a third option?)

once again: do you think the remount parameter error might be the cause of prolem?

again thanks for your support!
britt

[OErjan]

ouch, one syslog too many, sorry, /var/log/syslog was right.
hmm. i have no hddinstall of debina at pressent. hm, does the CD work with your pen?

Apologies for the delay. I got sidetracked while installing the system to my HDD as a full dual-boot XP/Debian installation. I got trapped chasing the "missing FAT32 partition" mystery, installing and configuring the proper nvidia video driver, and trying to get my winmodem working. No luck on the modem yet, but I've finally had some success. Lilo works, and I can now boot into either XP or Debian with a 1440x900 display. My CDROM works, too. Haven't tried wireless or PCMCIA yet (in either XP or Linux...) ACPI is sort of functional, as has been reported elsewhere. I'm a pretty happy camper right now.

(I'm using the 2.4.22 kernel.)

I got back to testing the USB stick and, much to my surprise, it now works! The system autodetects the USB drive when I plug it in, and unmounts it when I remove it. It automounts as /mnt/sda1, but I don't get a desktop icon in KDE. (I'll chase the icon problem later, *way* down the line, after I learn more about Linux and KDE.)

Here is the output from "dmesg|grep ub&&dmesg|grep sd&&dmesg|grep usb" after I insert the thumb drive:

Here's the output after I remove the thumb drive:

Notice the last two lines. You can clearly see the thumb recognized as it's inserted and removed.

OErjan, many thanks for bearing with me on this problem. I only wish I could tell you what I did to fix it, but I didn't do anything other than installing the system to HDD as a Debian install.

Best Regards,

Tom
