Issues mounting USB devices in Thunar under Openbox

Basically, whenever I attempt to mount a USB device in Thunar, I get a message that says:
Failed to mount "4.0 GB Filesystem
Not authorized
My .xinitrc looks like:
exec ck-launch-session dbus-launch openbox-session
It works when I use GDM to start openbox, but when I use slim, it fails no matter what I try. If anyone could help me out, I'd really appreciate it.

Check for *.pacnew files in '/etc/pam.d/' (specifically /etc/pam.d/slim.pacnew).

[SOLVED] Openbox+Thunar, how to show usb devices in thunar?

Hi. I've been running a pretty standard Xfce environment for a while. When I plug in a usb drive, I get a new item pop up in the "DEVICES" section of the left panel in thunar (note, it doesn't automount the device, it just shows that it's there and only mounts it when I click on it...I like this behaviour).
Now, I'm setting up an even lighter-weight environment, just openbox and tint2 with thunar as the file manager. But when I'm logged into the openbox environment, I don't get the item in the "DEVICES" section in thunar (but it still works fine in xfce).
If it run thunar from the command line and plug in a usb drive I get this message in the terminal
(thunar:21205): thunar-WARNING **: Failed to launch the volume manager (Failed to execute child process "thunar-volman" (No such file or directory)), make sure you have the "thunar-volman" package installed.
I don't see why I would need thunar-volman if it works fine in xfce. If I install thunar-volman and do the same, I get this message
thunar-volman: Unsupported USB device type.
thunar-volman: Unsupported USB device type.
thunar-volman: Unknown block device type.
So I'm wondering if maybe there is a daemon that is autostarted during an xfce session that makes thunar probe for devices to be plugged in or something like that. Why does it work in an xfce session, but not in an openbox session?

Thanks for your replies.
henk: I tried installing polkit-gnome and creating the rule as per the wiki, but it didn't work. Volume detection seems to work fine in xfce without this package.
jv2112: I added udiskie to .config/openbox/autostart and it seems to work. I've had problems with udiskie in the past; it seemed to have some trouble unmounting the drives properly after a write as I would find that the newly written files were corrupt. But it seems to be working fine.
I'll mark this as solved, but I'm still curious as to how xfce-thunar is mounting the usb devices.
One clue is that with udiskie, devices get mounted to /media, whereas in xfce they get mounted to /var/run/media/username/ (or something like that).

Can't mount usb devices as a normal user

Hi.
I woud like to ask for help. I've been struggling with some "bug" that i came with Arch and usb devices (disks, pendrives). I can't mount it as a normal user using KDE default mounting software (Dolphin, for an exmample). I can mount it only in therminal by using sudo privileages. Is there a way to fix it? I read it, the same problem:
https://bbs.archlinux.org/viewtopic.php?id=180025
I tried to check everything according this topic, also with udisk2 archwiki thread but on my desktop machine i just can't mount usb devices without root password. This is how the error looks like for a Dolphin:
<Over sized Image removed. URL link preserved>
This is the error, from picture
Error when trying to use acces to "removable device 7,5GB". System showed: The requested operation has failed. Error checking authorization:
GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: action org.freedesktop.udisks2.filesystem-mount is not registered (polkit-error-quark, 0)
Could somebody help me? I even installed udisk mounting tool to mont without root password, added 50-udisks.policy and it just does not work.
Help.
I can mount it wit terminal by typing
sudo mount /dev/sdXY /mnt/usb
than i'm asked for password and it is mounted. Don't know why i can't mount it without password when connecting usb devices to usb port.
moderator edit [ewaller]Removed link to over sized image.. Note, you set up a click through thumbnail correctly, but the "Thumbnail" was the same image and was too large

Could somebody help me? I even checked all rules in /etc/polkit-1/rules.d and /usr/share/polkit-1/actions on my notebook, and all files are the same with the same user permission but on notebook i can mount usb without problem, but on my desktop can't at all.

KDE mount USB device fails

Hi,
I am running KDE and having problems mounting USB devices via the KDE Device Notifier in the task bar. When I insert the USB stick there is the normal little popup giving me the option to open the flash drive in dolphin. When I click it, I get the following error:
"Could not mount the following device"
Mounting the device via terminal works fine. I also put my user into the "storage" group like the wiki tells me. Still no change.
Any ideas?

These kind of changes without notifications to users cause headaches. Someone was kind enough to update the wiki!
You are my personal hero for today, I was suffering the same problem. Manifests itself as 2 CK sessions listed by ck-launch-session, with the wrong session being marked as active.

[solved] Permissions issue - can't mount usb device as user, just root

In my last post I learned how to mount a secondary HDD from the command line. Problem is I did it as root. Now I have xfce4 running and I need mount permissions as user.
Here's my fstab:

....and these are the system messages I got when I plugged the device:
Unable to mount "74G Volume":
mount: only root can mount /dev/sdb3 on /media/disk3
Unable to mount "4G Volume":

What do I do here?

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?

MTP USB Device not recognized under Windows 7 Ultimate

Hey everybody, I'm sure there are plenty of similar threads about this issue, however I haven't seen any with Windows 7 as OS.
My problem is in the recognition of the driver, since the MTP device is not working properly. I've tried alot of possible solutions, but none of them have worked, i.e the removal of the driver in device manager, tried a custom script for the inf file, deleting of all USB/portable related drivers.
Its sad that no recovery tools are yet compatible with Windows 7, atleast not that I'm aware of.
Please, throw some more suggestions/ideas! My Zen works perfectly fine under XP btw.

I was having the same problem with my Zen Vision:M under Win7 Ultimate 64-bit.
No matter what I tried from deleting the usb root hubs and reinstalling drivers, nothing would get the mtp usb device driver to load.
I found that the mtp usb device driver will load correctly as long as you are plugging the USB cable into a direct port and not running it through a USB hub. At first I thought it might be due to an incorrect USB voltage, but the hub I'm using is a powered Belkin hub. Very strange!
So give that a shot -- run the USB straight to a port out the back of your computer. Don't use a USB hub or ports off your monitor since that is actually a hub as well.
Good luck!http://forums.mycreativefansite.com/...ify_inline.gif

Mounting USB devices in arch guest

I'm new to virtualbox, but not to linux. I have been using arch for at least 3 years, so I have some familiarity with it. I have recently installed arch as a guest OS on virtualbox (on OSX host). I am having some trouble accessing an attached USB device from the arch guest. I have defined the virtualbox USB filter for my device, and it appears to work, detecting the identified device and attaching it to the guest (at least as far as virtualbox is concerned). I can see the device in the virtualbox pull-down menu, and it shows with a "checkmark" next to it, showing (I think) that it has been attached to my arch guest.
Problem is, I cannot see the device from the arch guest. no entry in /dev for any USB device. symptoms are the same whether i insert ther USB device before or after starting the arch guest. I have HAL and dbus active in my guest. Also, I have made this work in arch installed natively. since there is no /dev entry, this might appear to be some form of udev issue? is there a specific udev setup that I should be aware of for arch as a guest?
Please help if you can. I will appreciate all comments and suggestions.
-dvh

hey, ive got Arch setup in virtualbox as well, and can mount usb's and cd's etc. (although with some issues i may need to bring up in another thread...) anyways, im assuming you have the PUEL virtualbox and not the OSE one?
also, your certain that you've mounted the correct USB (on the Virtual Box pull-down menu)? because you may have mounted a USB which was already attached to your host, and not the actual USB?
just checking, i dont know much about how to fix this issue so im just going at the simple solutions...

Mounting usb devices as non-root user ??

How can a non-root user mount a usb flash device?
As root, the device is mounted as:
mount -F pcfs /dev/dsk/c1tod0s2:c /mnt
The vfstab entry for this is as follows:
/dev/dsk/c1t0d0s2:c /dev/rdsk/c1t0d0s2 /flash pcfs 2 no -
This is running Solaris 8 on a SunBlade150

Hello.
I had the same problem.
If you do not have root rights on the computer the answer is: You cannot mount the device.
I had root access and I wrote a C program that (un-)mounted all possible device files (the "s2" devices as well as the "s2:c" devices because some flash devices come without partition table).
I chowned the file to root and set the "set effective user ID" bit in the file's permissions using chmod after logging in as root - so any user can start the program.
I think this is the most flexible variant because USB devices sometimes are assigned other device names.

Issues mounting USB using e17

I'm trying to get enlightenment's file manager to mount/unmount a USB stick via the right click menu.
However this causes it to segfault:
Output from dmesg

Also if I mount it manually then try to use the file manager to unmount it, nothing happens.
Suggestions?

It's now changed from a segfault to a problem with dbus:

[SOLVED] setting up permissions for mounted usb devices

Hi all,
I've been having the following problem when mounting my external hd: in order to mount the external hd I created a folder /mnt/usbstick/ giving permissions to a non-root user to read the files/directories in this folder (using chmod); however, after I mount the external hd, the set of permissions for /mnt/usbstick/ change so that a non-root user cannot read the mounted files in /mnt/usbstick. This is a problem for me because, when I copy a file from the external hd to the non-root home folder, the copied file can only be read by the root user.
Do you know how I can solve this problem? Should I write a udev rule and place it at /etc/udev/rules.d/? Or should I simply add the non-root user to a specific group from /etc/group? Any ideas?
Thanks!

You could try adding an entry for your usb device in /etc/fstab and specify the option user to let non-superusers mount it.
Here's an example of an entry for my external HD. I'm sure there are probably other (and better) ways to do this but it works for me.
UUID=4376-0BFB /media/FIRELITE vfat rw,user,noauto,async 0 0
Nice howto found on the wiki: http://wiki.archlinux.org/index.php/Fstab

Mount USB Device in Single User Mode

Hi All,
Can anyone give me any assistance of mounting a USB stick in single user mode?
I am trying to use the command:
$ mount -uw /dev/disk2s1 /Volumes/usb
But it get the error:
--specified device does not match mounted device
If I put the USB stick in normal OSX mode, then run 'df -k' in terminal, it is mounted by automounter, but I can't seem to get it to mount in single user mode.
Thanks,
Nik

Hi Nik,
   I don't believe that there are enough services started in Single User Mode to do this; you'll have to start the services yourself. However, I haven't tested this so I don't know. Wanna be a Guinea Pig?
   If your going to need to write to the boot drive, mount it read/write with:
/sbin/mount -uw /
Next, start the basic services, including diskarbitrationd:
/usr/libexec/registermach_bootstrapservers /etc/mach_init.d
The above should be one line, modulo wrapping. Then start diskarbitrationd:
/sbin/SystemStarter start Disks
You should probably check /dev and see what disks are already mounted. (without the USB stick) I assume that the services that mount removable media are now started so insert the stick and see if it appears mounted in /Volumes. Otherwise, check /dev and see if there's a new disk. If it only appears in /dev, you can use the standard mount command to mount it. If it doesn't appear in /dev then you might reboot into Single User Mode and repeat the procedure with the USB stick already inserted. If none of that works then this must not be the right method and you have my apologies.
Gary

Arch 2.6.36 not automatically mounting USB devices

Hi,
I am new to Arch but up to now i really like it and i am using this for my home server.
Now i use 2 external USB 1TB disks for backup which i auto mount using /etc/fstab.
The problem is that it is not auto mounting the volumes.
/etc/fstab
#External disks

It seems to recognize the physical disks but a mount is not performed?
Did i overlook something or is there something else wrong?
Thanks!

/etc/fstab is for FS options only, putting you device there does not guarantee automounting. This has already been discussed: https://bbs.archlinux.org/viewtopic.php?id=48469

[Solved] How to mount multi-device btrfs filesystem under systemd?

I am running full, native systemd. It always has an error during boot trying to mount my new, multi-device btrfs filesystem. There was no problem with mounting the filesystem when it resided on a single disk drive.
When it fails, it allows me to enter my root password and have a console. In this console, I can successfully mount the btrfs filesystem. Then boot continues normally, and then I can use the filesystem with no further problems, until the next reboot.
btrfs filesystem show /dev/sda4
failed to read /dev/sr0
Label: 'TimBTRFS' uuid: 317460bc-5b6a-4dac-acb8-7139dcbcff8b

devid 1 size 100.00GB used 42.02GB path /dev/sda4
Btrfs Btrfs v0.19
I looked up btrfs in the wiki, and it says I have to run "btrfs device scan" before I can mount the filesystem. "This is the purpose of the btrfs mkinitcpio hook or the USEBTRFS variable in /etc/rc.conf" I do not have an rc.conf. I do not know how to do this with systemd. What do I need to do to resolve this?

I added the btrfs hook as per the previous post. I ran "mkinitcpio -p linux". I ran grub-mkconfig. I rebooted and got the exact same problem. I did see the message early in the boot output that the btrfs hook was executed.
Here are the error messages:
[ 203.780864] device label TimBTRFS devid 1 transid 140 /dev/sda4
[ 203.781779] btrfs: disk space caching is enabled
[ 203.790133] btrfs: failed to read chunk tree on sda4
[ 203.790973] btrfs: open_ctree failed
Again, in the root console, I simply mounted the filesystem ("mount -t btrfs /dev/sda4 /btrfs"), typed Ctrl-d, and the bootup continued normally and successfully.
I need help, please.
