Debian Configuration :: USB Mass Storage Permissions ?
May 20, 2011
When I connect a USB stick to my laptop, it is mounted as root:root. I want ot be able to use it as the logged in user
It has worked in the past (1+ month ago), but recently it just mount it as root:root.
My userid is 1000, so somewhere in the system it knows that the current user is relevant.
The directory created
The date is off System time is correct - so this could be an indication of what is wrong.
I have tried with my own custom compiled kernel and now I am using the latest 2.6.38 official image.

Since I use openbox with some packages from Xfce4 (mainly for convenience) I get most stuff "for free" as it were when using openbox, but I can't figure out how to mount android devices in a simple way. I can either do it manually, or install some other file manager that has this capability. This leads me to my question, I've noticed that if I install Nautilus, which automatically mounts android devices OotB, I get this functionality in Thunar as well. This leads me to believe that there is clearly a dependency package of some kind installed when running apt-get install nautilus that enables it, It'd be great to get this functionality in Thunar without having all the nautilus packages just littering about for no good reason. the required package is gvfs-backends, which I should have realized when I was unable to browse smb:// addresses. You forget a lot when you only make a fresh install once every 2 years or so.

I am currently using opensuse 11.2 with kde 4.3.1. I am having a problem when I connect my samsung R450. It will not mount or show up as a usable device in either Dolphin, Amarok, or on the device notifier. I have tried manually mounting but I get an error saying it cannot find such device. I did not have any issues using it in 11.1 with KDE 4.2. It is being recognized by my system, but not allowing it to show up as a storage device or being mounted.
output of dmesg:
PHP Code:
output of lsusb:
PHP Code:
When I shut of the usb mass storage on the samsung R450 it switches to modem and is properly detected and usable as modem by my system.I don't have any other problems with other usb devices, such as a digital camera or flash drives, so I don't know if I just missing a system setting or configuring something wrong.

I just discovered that inserting any USB drive causes an immediate hang of the system. The keyboard caps lock and scroll lock lights blink. Only recourse is to power cycle the system. This is after installing Kubuntu 9.10 in January, I don't believe I had occasion to insert a USB drive until tonight. 100% reliable. No entries in logs, presumably because it hangs the kernel when it happens. The /var/log/kern.log file has been corrupted due to file system damage (1+ sectors of some other file inserted into chain) and probably other files as well.
I've not had occasion to report other bugs, but I've found no way to report anything other than application bugs. I tried using "ubuntu-bug kernel" which helpfully said there was no such application as 'kernel' and has been busy "collecting problem information" for the last half hour or more. Somehow I don't think its ever going to finish.
The crash only happens when booted into Kubuntu 9.10. If I boot off of 9.04 then USB drives work fine. Both USB drives I've tried reliably produce the crash. One is a random cheap USB thumb drive (imprinted "Cisco"), the other is a 16GB Corsair Voyager.

I have a problem when trying to mount a memory card in my cell phone. I connect the phone with an USB cable, select mass storage as the phone prompts it, but no luck.
dmesg shows
Code:
[ 200.673190] usb 3-1: new full speed USB device using ohci_hcd and address 4
[ 200.823377] usb 3-1: New USB device found, idVendor=05c6, idProduct=1000
[ 200.823386] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[Code].....
Just to be sure I tried the same thing with FreeBSD, though I knew from past experiences what to expect from it. It just worked(tm) flawlessly, but I'd rather not keep FreeBSD just for the sake of one device I can't seem to get working with Linux. All I can guess it must either be a kernel bug that has persisted for far too long or a faulty udev rule.

* I am implementing mass storage device on a test board.
* It contains NAND flash.
* Using corresponding "udc driver" and "g_file_storage" I could make my test board enumerate as mass storage device on my Linux machine.
* my 16 MB pen drive (test board) is now ready for read/write.
But there are some Bad Blocks on the NAND.Hence copy is not complete. Although on Linux machine there is no error message. Now , what is there in a normal pen drive which manages the Bad Block or what am I missing so that such Bad Blocks are managed.
Here is the error I get on my test board :
mtdblock: erase of region [0x2c0000, 0x4000] on "Bon 2" failed
end_request: I/O error, dev mtdblock2, sector 5664
Buffer I/O error on device mtdblock2, logical block 708

I am so completely frustrated with this and can't seem to find any solid answers. I have a Google Nexus One phone. I want to also use it as a portable music player. I can find no player for Linux that can do ALL of the following:
- copy music
- transcode when necessary
- transfer cover art in appropriate format
- transfer playlists (music files AND .m3u playlist files)
Banshee is the closest, but it is so painfully slow, has many problems with tags and also doesn't transfer playlist files. Banshee advertises support "out of the box" for this device. I've tried overriding with an .is_audio_player file, but it is ignored. Rhythmbox will transfer song files and transcode as necessary, but no artwork, no playlists. Exaile doesn't recognize this device for some reason.

How does the read & write request from a command prompt go to usb & retrieve the file ? When a read request is given , I/O manger sends the request to file system manager (FSM) and from FSM to mass storage device drivver and from there to mass storage , is this right in Linux ?

I've searched high and low, and can't figure this one out. I have a older Olympus Camera (2001 or so). When I plug in the USB connection, I get the following log output:
$ dmesg | grep sd
[20047.625076] sd 21:0:0:0: Attached scsi generic sg7 type 0
[20047.627922] sd 21:0:0:0: [sdg] Attached SCSI removable disk
Secondly, the drive is not mounted in the FS, but when I run gphoto2 I get the following error:
$ gphoto2 --list-config
*** Error ***
An error occurred in the io-library ('Could not lock the device'): Camera is already in use.
*** Error (-60: 'Could not lock the device') ***
What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed.
The output of gphoto2 is then:
# gphoto2 --list-config
/Camera Configuration/Picture Settings/resolution
/Camera Configuration/Picture Settings/shutter
/Camera Configuration/Picture Settings/aperture
/Camera Configuration/Picture Settings/color
/Camera Configuration/Picture Settings/flash
/Camera Configuration/Picture Settings/whitebalance

/Camera Configuration/Camera Settings/lcd-auto-shutoff
/Camera Configuration/Camera Settings/camera-power-save
/Camera Configuration/Camera Settings/host-power-save
/Camera Configuration/Camera Settings/timefmt
Some things I've tried already are sdparm and sg3_utils, however I am unfamiliar with them, so it's possible I just didn't find the right command.
# mount | grep sdg
# mount | grep sg7
# umount /dev/sg7
umount: /dev/sg7: not mounted
# umount /dev/sdg
umount: /dev/sdg: not mounted
# gphoto2 --list-config
*** Error ***

I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.

It doesn't show it on the device-notifier, or fdisk, and not sure if this will be any use to you. In windows it appears immediately as a MSD, doesn't show as a modem or anything first.

I need to enable my new E2120 samsung phone as a mass storage device. but I think I need a USB driver. Had a good look round the forums but can't seem to find any posts. Its quite a new phone but hopefully the solution is already about. When I plug it into the USB the phones screen has a hashed out 'mass storage' option.

I would like to download a few (591)images from the Galaxy S phone. Samsung have advised me that to do that I need to place the Galaxy S phone on Mass storage, whivch I can do and plug the phone USB cable to the PC and manually mount the USB. The Galaxy S firmware 2.1-update1 doesn't support automatic mounting! The Galaxy S has an Android platform Kernel version 2.6.29 with root @SE-S604 #2. I'm running Ubuntu 10.04 on a AMD Athlon(tm) XP 1700+ with 1G of ram. It's the manual mounting of the USB connection

I recently backed up my home folder onto another HD. When I tried to transfer the files from the other HD back to the original HD after a fresh ubuntu install I noticed all my files were restricted to root access. Even after moving the files back via root access I can still only access them that way. Is there a way to mass change the permissions to all the files and folders within my original home folder?

I'm interested in buying a new hardware for my company. The old server (now 10 years old) should be replaced with a new one. Till now, I was looking on different hardware suppliers, boards and different other places. I found a Tyan board [URL]. The hardware spec is quite interesting and the board would fullfill our claims.
how both storage devices will be supported by Ubuntu or Debian??
- SATA-Controller: AMD SP5100
- SAS-Controller: LSI 1068E

my ENTIRE hard drive now has user AND group permissions root. I can't start X and are having various permissions issues. although ive been using linux for a long time.
long story long, I did a debian netinst to my netbooks SSD. got everything EXACTLY as I wanted it, was very happy with my first go at debian but of course being a linux dork im always willing to tweak. I installed onto btrfs which I recently learned supports compression which not only saved precious SSD space (only 8GBs) but according to some benchmarks also improved performance. this was a boot option and would only start compressing new files. this, of course, could not be good enough. so I formatted my SD card btrfs, mounted it with compress option + my SSD defaults and copied over all files that weren't a mount (i.e. proc, dev, sys,...) however I forgot to copy permissions. so every file was copied with root:root ownership and I didn't realize this when booting to the SD card to verify things were working as I assumed ( never do this ) that getting to a login terminal was enough. So now I need to fix all permissions and I would really prefer it be without a clean install.
A netinst can take a dec amount of time and I had a lot of tweaking to do since I only used Xorg + i3 tiling wm. there has to be a way to fix this...I started trying to reinstall all the packages but kept running into issued where aptitude wasn't able to reinstall things like bash or perl-base, presumably bc they were in use or had incorrect permissions set

I just installed LAMP server and it works. Anyway, I have problems with permissions to www/. I can't access it! Its located in /srv/www.
What do you suggest? I need to be able to freely add/modify/remove files under www/ as 'dagrevis' (not 'root').

I am trying to figure out what needs to be done to automatically set read/write permissions for everyone for my proprietary USB device on system boot. I have created a udev rules file which changes the permissions for the device when it is connected, but it does not change the permissions when the system is booted with the device already connected. The file looks like this:
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="our vendor id", MODE="0666"
Does something else need to be added to the rules file to make it work when the system boots with the device connected? Is there some other script which needs to be created somewhere?

I'm trying to allow non-root account to use avrdude to program mucrocontrollers. There are many articles online about how to do that, but it seems not to work for me. Every time i try to execute avrdude it says "permission denied". Here's "$ udevadm info --name=/dev/bus/usb/002/011 --attribute-walk" says looking at device '/devices/pci0000:00/0000:00:1d.1/usb2/2-1':
KERNEL=="2-1"
SUBSYSTEM=="usb"
DRIVER=="usb"
ATTR{configuration}==""
[code]....
However, after restarting udev, replugging the device, even rebooting the computer I still get "permission denied". The Vendor and Product match, so what's the problem?

I'm trying to mount a remove filesystem onto my own server. I am able to do this, however I can only access it as root, or if I chmod 777 the lot. Obviously I want to be as secure as possible, so I'd like to avoid either one of those options. Another option is to mount it directly into my home directory, but previously when I was trying out Ubuntu this caused Samba problems - and I was advised mounting in my home dir was a workaround rather than a proper fix.
I have root access with sudo on my own server. I've not set a root pasword, and until I need to I'll avoid it. I have a user account with full control over my own home directory on the remote server. I am mounting using fstab - sshfs#username@remoteserver:/media/sdk/home/username/ /media//remote/ fuse user,idmap=user 0 0
What I would like to do is without changing the permissions on the remote server change the permissions when they are mounted on my own server. I would like them to be in the group sambausers for example. Instead they are owned by root and in the group of 1024 (which I have not set). Additionally for this to work they would have to have 770 on my home server and 700 on the remote server....

First let me say that Lubuntu is a lightweight version of Ubuntu, so there is not much point in loading it up with unnecessary packages. If you just want to share printers on a Linux network, you don't need Samba. And if you just want a way that users can "push" files to others on a network, use Giver (+ Avahi) as this is a better option. Especially as it sorts out file permissions for you.
To enable file sharing on a Lubuntu 10.10 machine, go to Preferences > Synaptic Package Manager and add the following:-
* samba
* system-config-samba
* gvfs-bin
* gvfs-backends
...accepting any dependancies, 11 packages in total.
I suggest you re-boot now. As an initial test, go to file manager (pcmanfm) and enter:-
smb://localhost
You should see the local print$ folder listed.
To access folder shares remotely
* open file manager (pcmanfm)
* enter the IP address or computer name of the machine you wish to access
e.g. smb://192.168.0.99 or smb://print-server
To share a folder:-
Go to: Preferences > Samba (enter password when requested)
In the Samba Configuration screen:-
* File > Add Share
* use Browse... to select folder to be shared
* Tick "Visible" and (if required} "Writable"
* In the "Access" select "Allow access to everyone"
Set the Linux permissions:-
* locate the folder to share in file manager
* right click on the folder and select Properties > Permissions
* set the required permissions, e.g. Other: Read & Write (to allow anyone full access)
