udev assigns wrong group to USB device partition

[Damon W]

I am running Breezy on a Dell Inspiron 6000 (though the same problem exists on
Compaq Armada m300).

All packages are up-to-date.

When a Sandisk 1Gb USB Storage device is plugged into USB port, "Sandisk Cruzer
Mini" shows up in the "Computer" section. However, it is not automounted. When I
right-click and choose "Mount Volume" I receive an error:
"Unable to mount selected volume." Details: "mount: can't find /dev/sdb in
/etc/fstab or /etc/mtab"

The device is /dev/sdb1, NOT just /dev/sdb.

The only way I am able to mount the device with r/w/x permissions for the
current user is to "pmount /dev/sdb1 usbdisk". This then mounts the device and
shows it on the desktop and the "Places" menu as "usbdisk".

Please see attachments for more technical info. If there is anything else you
need to help fix this, just let me know.

The same problem (lack of automount, GUI mount not working) exists with my Ipod
mini, which acts as a mass storage device.

Both the Ipod Mini and Cruzer Mini automounted in Hoary without problems.

[Warren Butler (warrenbutler1)]

Same problem here.

Dell Latitude CPi, Breezy will all the latest updates

Same problem (same behaviour and messages), and same workaround.

Did work with Hoary.

I believe this bug is related to the removal of the function sysfs_get_device_parent() from kernels 2.6.12 and greater.
I have built the latest libsysfs1 from debian, which has just addressed this bug and now my devices are being automounted.

I am running hoary, but if the problem is in breezy I guess its due to breezy needing an updated libsysfs

Please see

Breezy has an up to date version for months:

 libsysfs1 | 1.3.0-2 | http://archive.ubuntu.com breezy/main Packages
sysfsutils | 1.3.0-2 | http://archive.ubuntu.com breezy/main Sources

Right, the kernel correctly recognizes it, but it is not known to hal.

If the device is plugged in, can you please show me the output of

  ls -l /dev/sdb*

? Also, can you please try to get a full hal debugging output as described on
the second half of

  https://wiki.ubuntu.com/DebuggingRemovableDevices

Thanks!

Output:

brw-rw---- 1 root disk 8, 17 2005-07-29 18:09 /dev/sdb1

Running the command as specified says that --drop-privileges is an unrecognized
option. Omitting that option gives the attached hal.log file.

You're welcome... Thank you!

Hah, my gut feeling was right. sdb1 has the wrong group, so hal cannot read the
device.

Ah, right, I updated the page; In Breezy, --drop-privileges doesn't exist any
more (it's the default), and there is now a --retain-privileges switch. Anyway,
we have to debug udev now, which seems to be the actual cause of that bug.

If the device is plugged in, can you please do:

   sudo sh -x /etc/udev/scripts/removable.sh sdb > removable-sdb.txt 2>&1
   sudo sh -x /etc/udev/scripts/removable.sh sdb1 > removable-sdb1.txt 2>&1

and attach removable-sdb.txt and removable-sdb1.txt here?

> If the device is plugged in, can you please do:

Gives:
sh: /etc/udev/scripts/removable.sh: No such file or directory

> sudo sh -x /etc/udev/scripts/removable.sh sdb1 > removable-sdb1.txt 2>&1
gives same output.

Here is the result of ls /etc/udev/scripts :
cdsymlinks.sh ide-devfs.sh inputdev.sh scsi-devfs.sh
dvb.sh ide-model.sh raid-devfs.sh

Meh. So this is not Hoary, but Warty, I assume. Is it in /etc/udev? Can you
please do the same with /etc/udev/removable.sh?

Thanks

Sorry to jump in like this, but I'm having the same problem.
I think that Daemon is running Breezy (like myself) and unfortunately there is
no /etc/udev/removable.sh in Breezy.

I'd be happy to help with anything to fix this bug. I want my ipod to mount
automagically again =)

[Martin Pitt (pitti)]

I think this is really a dup of #13520. Can you please upgrade to the latest
udev (0.060-1ubuntu6) and check again?

Sure thing, that did it. For some reason my udev wasn't up to date.
The remaining things seems to be covered in #13520.

Sorry for the noice and thanks for the good work.
