i'm upgrading my system from slackware 11.0 (kernel 2.6.20.4) to slackware 12.2 (kernel 2.6.27.7)

the new kernel is compiled starting from the same .config of the old.

All work fine, except for my HITACHI HDC-763E digital camera (Vivitar, Inc) that i cannot mount or partition.

In slack 11.0 I mounted it like a usb mass-storage device; and now I can't. I try to compile the old kernel in slack 12.2 and it still doesn't work.

So, I suppose I forget some packeges of slackware. Other usb mass-storage disk work fine. I don't think it's a kernel problem.



This is my logs:

Maybe take a look at /etc/group to ensure that your user has permission to mount the device. just a thought.

As there are a lot of differences between 2.6.20.4 and 2.6.27.7 I would install one of the stock 2.6.27.7 kernels instead of re-using the old .config otherwise you could miss some important stuff. And it is very possible that some software in 12.2 simply won't work with your old kernel. It will always be possible to customize the new kernel after you have checked that everything works with the stock one if you like or need.

Not to miss any package during the upgrade, I would have done this
1) install slackpkg (included in 2.2) then edit /etc/slackpkg/mirrors to un comment one mirror as stated in the file
2) slackpkg update
3) slackpkg update-gpg
4) slackpkg glibc-solibs # a lot of other packages rely in this one, which should be at the good version
4) slackpkg upgrade-all # does what it says
5) slackpkg install-new # to get new packages of course, aka those not included in 11.0
6) slackpkg clean-system # to remove obsolete packages and all other packages no included in 12.2, unless you un check it when asked
7) slackpkg new-config # to check all modified configuration files, replace or update the old ones

As you will have installed a new kernel, check/edit /etc/lilo.conf and run lilo

Of course make executable the (possibly new) scripts you need to run in /etc/rc.d

And remember that UDEV's usage is almost mandatory in slackware 12.2.

Anyhow, as 12.2 very different from 11.0, my feeling is you would have been better off making a clean new install than upgrading.

About groups, following Hitest's post, check that your regular users are members of plugdev group (as well audio, cdrom, floppy, video and may be lp as needed).

Sorry, in fact i installed 12.2 in another disk with almost packages that i used in 11.0.
Now i've re-installed with every packages of 12.2: during installation i plugged the camera in usb port, and installation recognized it, and i mounted it as vfat from second console.

But when i started with kernel distribuited whit slack hugesmp i still could not mount my camera.

i'm asking me what kind of kernel is running during installation while i suppose that huge fully support devices?

By default the same huge-smp kernel is used during installation.

Did you try to mount the camera as root or as a regular user ? In the latter case, which groups is this regular user member of (you can check with "cat /etc/group|grep <user>"). Is (s)he member of "plugdev" (I suppose you use KDE ?) ?.

Anyway first try to mount it as root.

Please send output of "dmesg|tail" again 30 seconds after having plugged in the camera, as well as the output of "lsmod" whilst the camera is still plugged-in.

I mount the camera as root. Now I re-compiled the kernel with the config file in kernel/hugesmp.s directory of slackware without any good news...
Now all USB support is compiled built-in the kernel.
Here are the logs. Thanks a lot for your collaboration!

With gphoto2/libgphoto2 packages now inlcuded in Slackware 12.2, you should not need to mount the camera manually (and especially as root).

Did you check that your camera is configured to connect to a PC in PTP mode and not as a USB storage device?

My father's camera (BENQ something) wouldn't be recognized until I switched the connection mode to PTP. And then, the camera was automatically recognized and mounted with my normal user.

Sorry, no clue.

We still see these errors messages in dmesg's outpt e.g.:
end_request: I/O error, dev sdc, sector 4095488
which probably prevent you to mount the device as /dev/sdc1 though you have following line too in dmesg's output:
sdc: sdc1

I think your problem is related to that, but do not see what can cause these messages.

I understand that you eventually made a full install or Slackware 12.2 from scratch. If that's hopefully true you could try to switch to kernel-generic-2.6.27.7-i486-1; check that kernel-modules-smp-2.6.27.7_smp-i686-1 package be installed as well, do not forget to make an initrd (see /boot/README.initrd) to include your root partition's file system module, edit /etc/lilo.conf accordingly then run lilo.

But to be honest, I'm afraid this will not solve your problem.

I wonder if your SD card might have gotten messed up somehow. If there are now no important images on it I would reformat it in the camera (something you should do anyway from time to time) to be sure that your problem is not about card errors.

The messages appears in dmesg some seconds after "usb-storage: device scan complete"
and after mount command or other commands that i try to do on /dev/sdc1.
"mount -t vfat /dev/sdc1 /MYUSB" answers: can't read super-block

Every command on device fail. So I cannot do fdisk or re-create fat partition.

I was not talking about fdisk but about the camera. Most cameras have the ability (look in your manual or the menus of your camera) to format new storage cards. If you delete single pictures, maybe edit some (all in the camera) and so on there can occur errors on the card. That's why some people suggest to (re)format the card (in the camera) every time it's inserted.

The camera is new, I format the memory before first use with the camera;

I reformated it after the errors while tried to mount with slack 12; but when i succesfully mount in slack 11 and even 12 on other pc, I suppose that something is wrong in my slack installation or kernel compilation...

This evening at home I'll try another time.

Thank you for interesting,
Pierpaolo

A useful exercise may be to remove the flash memory from the camera, and insert it into a (USB) card reader. This may expose whether the problem lies with the card, or the camera. Universal media card readers can be purchased for under $15 in my locale.
--- rod.

I stopped the udev service and i can mount the camera.
I think the problem is in the udev 1.35 of slack 12.2!

log of udevadm monitor is ready!

Other trial and result come soon as possible.

Bye,
Pierpaolo
