Mounting USB-Devices only works as root

Hi!
I am having a problem with USB-Devices on my ARCH using KDE.
I can only mount them
- as root
and only manually (not using HAL) with "mount /dev/sdc1 -t vfat /mnt/disk" in a terminal.

The presented error (as user) is this:

A security policy in place prevents this sender from sending this message to this recipient, see message bus configuration file (rejected message had interface "org.freedesktop.Hal.Device.Volume" member "Mount" error name "(unset)" destination "org.freedesktop.Hal")

When i try to open the (not mounted) device in Konqueror as root it simply says "authorisation not granted"

After mounting the device, i can edit/delete files as root but not as standard user.

Unmounting only works manually, too, the error when i try to unmount the device in konqueror is

Device to unmount is not in /media/.hal-mtab so it is not mounted by HAL

(Which sounds reasonable)

What can be the reason for this?

Thanks in advance, Hauke

Re: Mounting USB-Devices only works as root

are you a member of the storage group?

gpasswd -a user storage
you may want to add yourself to optical as well, if you need to use cd/dvd drives.

Re: Mounting USB-Devices only works as root

I have the same problem on KDE. The user is in the storage and optical groups.

LOL

It's fixed now. I forgot to restart hal after adding the user to those groups

Re: Mounting USB-Devices only works as root

Yeah, worked for me, too - never heard of the "storage" group though ;-)
I already had thought of "hal" "dbus" but "storage" ;-)

Thanks a lot

Re: Mounting USB-Devices only works as root

I'm experiencing somewhat similar problems. The problem is that everything seems to be configured correctly:

- I'm in the hal,dbus and storage and logged out and in several times

[luk@travelmate ~]$ groups
wheel games dbus hal video audio optical storage scanner camera

- Mounting with mount works (as root, of course), so my HDD isn't failing.

- Hal detects my external HardDisk and KDE's media:/ recognises my internal HDD and my CD, so hal isn't failing either

[luk@travelmate ~]$ lshal -m

Just for the sake of completeness, te last part of my pacman.log. I reinstalled kdelibs, kdebase, dbus and hal to make sure there wouldn't be any coruppted files.

Re: Mounting USB-Devices only works as root

I'm having problems with both my external disk and a regular USB stick.

Re: Mounting USB-Devices only works as root

I had to chmod 777 my mountpoint in order to read/write as user to both fat32 and ext3 filesystems on external drives
