Cant access usb-devices anymore

Svlad Cjelli · 2010-02-14 10:27:59

Hey guys,

it is strange, but i cannot automount or access usb-devices anymore.

I am in the storage-group

id says:

uid=1000(philipp) gid=100(users) Gruppen=100(users),7(lp),10(wheel),82(hal),90(network),91(video),92(audio),93(optical),94(floppy),95(storage)

When i open nautilus or pcmanfm as root i can browse the data on the device, but as normal user i
can't

Can somebody help me?

What does your fstab look like, do you get any errors when you mount you drives? You need to give us more information.

Svlad Cjelli · 2010-02-14 18:10:45

Ok,

so this is my fstab:

# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0

#/dev/cdrom             /media/cd   auto    ro,user,noauto,unhide   0      0
#/dev/dvd               /media/dvd  auto    ro,user,noauto,unhide   0      0
#/dev/fd0               /media/fl   auto    user,noauto             0      0

/dev/sda2 / ext4 defaults,noatime 0 0
/dev/sda3 swap swap defaults 0 0
/dev/sda4 /media/Data ntfs-3g auto,users,rw,noatime 0 0

But i never managed mounting usb-devices via fstab.
I never had any problems until now...

The error-message i get when i plug in the usb-device is the following:

If i then want to access the device via pcmanfm the next error pops up:

Do you

Check the HAL section in wiki .

pyther · 2010-02-14 18:33:20

What happens if you manually mount the drive (with the entry you have in fstab)?

Ok i did, and i edited some .fdi-files from the troubleshooting-section..

Nothing happened. I CAN browse the files if i open a file-manager as root, but i cant as normal user.

I dont have any line regarding my usb-device in fstab. And i do not want to mount them via fstab. I just want to have plug'n'play :-(

pyther · 2010-02-14 18:43:16

Well try to manually mount it first. What file-system is it using?

Svlad Cjelli · 2010-02-14 18:55:18

It uses fat16...

I think it is mounted when i plug in the device... i simply cannot browse it because i am "not authorized".

I had the same problem some time ago...
It is solved on Polish Arch Linux forum http://forum.archlinux.pl/viewtopic.php?id=4409
I think google translator will help.
If not, there is second post by user "hash", and the first code is that, which you must add to /etc/dbus-1/system.d/hal.conf
Also, edit /etc/group and add yourself to "plugdev" group.
For me it worked.

Dzenkyu,and sorry for copying your post. but I need to save this page with full info ))

Hi,

that does not work for me

I edited the hal.conf, but i cannot add my user to plugdev, because plugdev does not exist

[root@winchester ~]# gpasswd -a philipp plugdev
gpasswd: group 'plugdev' does not exist in /etc/group

What can i do?

EDIT:
I added a group via

groupadd plugdev

and made myself a member...

I still can't access my usb-device :-(

I asume that you are using startx or slim?

change the line that starts your wm/de to "exec ck-launch-session yourwm"

HOORRAAYY! Thats it. I just switched from gdm to slim.

What does this "ck-lauch" mean?

Thank you so much Mr.Elendig!

Hello,
Make sure you have dbus enabled as a daemon in nano /etc/rc.conf....that will fix your problem the right way I believe. For the GDM, that is:)

http://wiki.archlinux.org/index.php/Ude … if_present and commented out my usb entries on my fstab It just works for me.
