[SOLVED] Cannot mount usb (as normal user)

Hello
I'm facing this problem for the first time, but can't tell if it came after an update or an unexpected reboot (light went out).
I'm using latest kde (4.9.2?), and the latest kernel,
Linux gantz 3.6.6-1-ARCH #1 SMP PREEMPT Mon Nov 5 11:57:22 CET 2012 x86_64 GNU/Linux
When I plug any usb device, kde ask me what to do. When trying to mount it, either from the kde "mount" plasmoid or from dolphin, I get a "Not authorized" error. Mounting via cli with sudo works fine.
After doing some research, I found that I need to be in the storage group in order to be able to mount, so I checked, and I was already on the storage group. Next.
More research sent me to lots of pages talking abour .xinitrc, wich doesn't exists (on my home, at least). Also tons of pages where talking about somethin like "exec ck-launch-session dbus-launch session-manager" (I login via kdm), but the ck-launch-session is not found on my computer either.
So i'm stucked right now, and don't know how to proceed, any clues? Thanks

pd @Raynman: removing myself from the storage group did not change anything.
that's not a fix, it's a crappy workaround. You are not supposed to touch these files, they will be overwritten on an upgrade. My guess is that you are simply not using systemd and therefore you are not in an active logind session. You have to boot with systemd, as mentioned in the news. Everything should then just work out of the box.

[SOLVED] Cannot start JACK as normal user

Hello,
I cannot start JACK as non-root user. As root, everything works as expected. The user is a member of the audio group, but apparently this system is deprecated anyway.

I have found similar threads, but all differ from my situation and the solutions suggested do not seem to work for me. Some people suspect PulseAudio to be the culprit, I tried to redirect ALSA to PulseAudio, and that to JACK without any effect. I don't think I use PulseAudio, but then again, I run Gnome, and gnome-settings-daemon seems to depend on it.
Any suggestions are much appreciated!
Thank you.

Hey ids1024,
thank you for your answer. I am now using PulseAudio (which was indeed installed before, but somehow didn't start at boot), and it works very well, also with JACK - as long as I run jack_control as root. As a normal user, it's the same issue as before. I'm not sure if PulseAudio has anything to do with that at all.
EDIT: I installed pulseaudio-alsa. Now I can start JACK as non-root user! However, JACK - although it registers with PulseAudio, as shown by pavucontrol - doesn't output any sound. Unless I'm root, of course.

[solved] cannot start koffice as normal user

Hello,
after having had no problems with koffice for a long time, i lately fail to open any koffice Program as normal user (as root i still can open them) getting always a similar error message (just the program name is changing; here it is the message for krita):

Please help me getting koffice programs to start as a normal user again,

Permissions seemed to be set all right and removing the config files in my home directory couldn't convince koffice to start, but removing also the files under /var/tmp and /tmp finally helped. Thanks for the way leading advice,

Cannot mount USB disk in SIngle-user mode (solaris 10)

Hi all ,
I need some help please :
I can read/write to my USB disks when i'm in muti-user mode but when to I swith to single-user mode ( init S ), I cannot mount it.
in Single-user mode , i started volume management daemon :
#/etc/init.d/volgmt start
#volcheck
but i'm still not able to mount it.
I tried to mount manually:
#mount /dev/dsk/c2t0d0p0 /testpoint , i have this error: < mount : not a UFS magic number ( 0x0) , dev/dsk/c2t0d0p0 is not of this fstype.
My system recognizes the USB device though in single-user mode:
This is an output of #iostat -En

Hi ,
thanks for your advice. My problem is resolved.
The USB drive was actually a FAT filesystem.
so I did # mount -F pcfs /dev/dsk/c2t0d0p0:c /testpoint and everything went fine
I can read/write to my USB disks when i'm in
muti-user mode but when to I swith to single-user
mode ( init S ), I cannot mount it.
in Single-user mode , i started volume management
daemon :
/etc/init.d/volgmt start
#volcheck
but i'm still not able to mount it.It probably requires other items to be started
first.
I tried to mount manually:
#mount /dev/dsk/c2t0d0p0 /testpoint , i have
this
error: < mount : not a UFS magic number ( 0x0) ,
dev/dsk/c2t0d0p0 is not of this fstype.
Looks like it's assuming UFS. If this is a pcfs
filesystem, give it the type on the mount line.
# mount -F pcfs /dev/dsk/c2t0d0p0 /testpointYeah, this was the right command, I had to specify option < -F pcfs >.
but I read somethere on this forum i had to specify :c as the drive for FAT at the end of c2t0d0p0 , so the full command was:
# mount -F pcfs /dev/dsk/c2t0d0p0:c /testpoint

Usb drive mount by a normal user

how can i make a normal user mount usb drives? i added a line in fstab that allows users to mount /dev/sdb1, but this solves only partially the problem

After a recent sys upgrade, I am having a somewhat similar problem. I can still mount my usb stick, but the permissions are now a little screwy (EDIT: i.e. permission denied when trying to change into /mnt/usb directory).
fstab entry:
/dev/sdc1 /mnt/usb vfat rw,user,noauto 0 0
after performing a mount /mnt/usb the permissions on /mnt are:
d-wxrw-rwx 6 root users 16384 1969-12-31 19:00 usb
well, the permissions on this drive seem strange to me, as well as the 1969 date. Additionally if I look at the directory as root everything is executable, which should not be the case. I've added my username to users and storage in /etc/groups to no effect. I can mount fine using pmount, but I would much prefer things my way, plus i dislike the idea of being forced to mount things under /media (notions of liberty and such)
Any thoughts or additional info needed? I've become stumped enough by this odd behavior to actually register and post.

[SOLVED][XFCE] Cannot mount usb disks & manage network connections

Hi guys,
I'm using XFCE with 3.3.1-1 kernel. Since yesterday I'm not able anymore to automatically mount usb disks, manage my WiFi networks (networkmanage connects to the default access point but I can't select another AP nor editing my settings). I'm also prompted to type my password when I clik on the shutdown icon;
So it seems I lost some privileges but I can't figured out why...
I still belong to the same grousp as before:

Does anybody has an idea where to take a look?

I'm about up to my wits end trying to allow my normal user to mount and unmount my cdrom drives...
Here's my /etc/fstab

I also added a new group called "mount" and added both root and my normal user to it.
I then did
chgrp mount /bin/*mount to change mount and umount to the mount group
then i did a
chmod 774 /bin/*mount
I also made sure that the 3 mount directorys in fstab existed and gave them 777 permissions...
Did a complete reboot... and the normal user still can't use mount... I get this error...
mount: must be superuser to use mount
I'm at my wits end. I believe fstab is correct. I believe my permissions are set correctly... Is there anything else I need to do?
Thanks in advance for any replies...

I have a Gen 2 connected right now, it most definitely uses UMS. I have a Gen 4 at home that also uses UMS. I've got to assume your Gen 3 would as well.
Does it go to the "USB Drive Mode" screen when you plug it in?
Edit: Do remember having an issue one time where it would not go into USB mode. Rebooting the Kindle fixed it. On my Gen 2, you would go to the Home screen, then hit menu and settings, hit menu again and there's an option for "Restart".

Mr. Elendig:
Why not use automounting instead?
To install Arch packages I needed an Internet connection, which required use of a Sierra Wireless card, which required chatscripts stored on another filesystem. In my first Arch forum post ever, the one preceding this one, I learned to mount a device by creating a mountpoint in /media then invoking #mount. After installing all packages and creating a user name, I signed on with xfce4 and plugged in the usb device again. It didn't mount. So I did it manually using sudo. Since that worked I had the idea that adding the mountpoints to /etc/fstab would be useful, so I did. When that didn't work I decided to just ask for help.
So sure, I'm down for some automounting action. How do I do it?

Domain User cannot mount USB or shutdown

Hello,
after a few weeks when I installed Samba and joined a Domain I realized that when I put in an USB stick my file manager tells me that this operation is not allowed. So I have to mount the USB stick with sudo. Did I make something wrong in the PAM configuration? My domain user is in the local group of storage and power ...
It would be great if some one can give me some direction where to look for the problem.

So, why did the reboot work ? (asked rhetorically)
Unlike some other famous operating systems,it is not likely that you machine had reached some unstable state requiring a restart to put it into a known state.
In your case, you probably updated the kernel. When this happens, the kernel modules on disk for the running kernel are replaced by those for the new kernel. After you did the upgrade, you plugged in your USB device. The kernel looked for its modules, but they were gone -- replaced by those for the new kernel. After rebooting, you are now running the kernel that matches the installed modules.

my problem is when i mount the usb /home/corsair8gb the users and groups become root. is this normal for usb drives. it does not happen when the samsung1tb is mounted, so was wondering how i can mount the corsair8gb without changing the users and groups of the directory i mount it to???
NOTE: /home/corsair8gb directory user is myusername and group is users when device is not mounted.

Have you tried the option user instead of users? It's not exactly the same.
Edit: To enforce it you can also set the user/group id by uid=<youruserid>,gid=<yourgroupid> .
Note that these are numbers, to find them e.g. issue "id" in a terminal.
ok i will try this way. i did try before. didnt realise it was with codes.

Cannot mount USB Hard Drive (750GB LaCie Desktop Hard Disk USB2 K)

I recently purchased a 750GB LaCie Desktop Hard Disk USB2 K, and used it to back-up my NAS (Ready NAS NV+). Now I want to transfer some of this data on the Lacie at a separate location to a Time Capsule, via my MacBook. When I insert the USB cable into TC it seems to recognize the disk, but I cannot see the contents (I have a separate post on this).
WHen I insert the USB cable into my MacBook, I get the message:
"The Disk you inserted was not readable by this computer."
I (THOUGHT) I had formatted the disc as ext3, but do not recall (and cannot access my notes remotely). Is there anyway I can use disk utility to check the formatting, or does the message above give the game away?
Any thoughts appreciated!

I did not think that EXT3 support was built into OS X. There are various utilities around but I do not know how well they work and they would only be useful for the Macbook.

My app cannot use USB when ordinary user

Hi,
I have written an application that controls a USB Phidget servo via libusb, but when I log is as an ordinary user my app cannot communicate with the servo. As far as I can tell the problem is that when an ordinary user, my app cannot use libusb. But I can generally use other USB devices like flash drives or digital cameras.
It may be a matter of adding my self to a group but can't figure out which (there seems to be no usb group in /etc/group.
Any ideas/hints please?
My thanks in advance.

I know even less...;) but I found out what I did wrong, rather silly in retrospect but as I said, never had to fiddle with udev: I added the usb group but did not add GROUP="usb" to the udev usb_device rule. Now its OK, thank for the tip!
