Ubuntu :: Kernel Lock With Usb Mass Storage Device ?
Feb 2, 2010
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'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/Picture Settings/focus-mode
/Camera Configuration/Picture Settings/focus-pos
/Camera Configuration/Picture Settings/exp
/Camera Configuration/Picture Settings/exp-meter
/Camera Configuration/Picture Settings/zoom

/Camera Configuration/Picture Settings/iso

/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 ***
An error occurred in the io-library ('Could not lock the device'): Camera is already in use.
*** Error (-60: 'Could not lock the device') ***

here we have an older digicam (Jenoptik/Exakta Model "DC 22", if someone might want to know) that can be switched between some "PC Camera mode" and "Mass storage mode".Unfortunately, if attached to USB, it is always recognized as

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:

output of lsusb:

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 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 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.

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.

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.

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.

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.

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.

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.

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 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 am using a Belkin F5D 8235-4 ver 2 wireless router. My linux box is connected direct. I have a 16G flash drive installed in the usb port on the router that I want to use for storage so I can dump files I share with my other machines on the network. Windows sees this usb and works fine by just using the web browser and using 192.168.2.1usb no problem. Then I try to use my unbuntu and can not for the life of me figure out how to set up a permanent link to that drive in linux. I would like to have a direct connection on my desktop. Of course I tried Belkin and was told we do not support Linux.

Are there any tools in Ubuntu that could defragment my MP4 player (Sansa E280R)? One of the songs on my MP4 player isn't showing its Album Name or Artist Name. I know I have the artist and album name tagged onto the MP3 because I set them both & double checked using mp3tag.

I had troubles with my NTFS external hdd mounting without becoming root until I changed my fstab file. However after changing my fstab file I created an error in the place of the one I had fixed. Now since the change I have two entries of my external hard drive in Places. I'd like to know how to remove the duplicate entry.
Provided is my current fstab and screenshot of duplicate:

I am running Fedora 12 OS on my machine. I would like to disable the USB devices for normal users so that usb-storage devices cannot be plugged in. However at the same time a mouse or a keypad may/could have a usb connection. note that root should be able to use the usb storage devices. How can the same be done on fedora 12? I would prefer not to do it via the BIOS options.

I just upgraded to 15 and was wondering if it was possible to specify which devices to prioritize a route through. I have my machine, a laptop, connected to my family's router for an internet connection and a wired connection to a personal router for a faster and private connection between my other two computers and a network storage device. Whenever the laptop is connected to my personal router everything goes through it and it can't connect to any external web sites. But when I unplug it and go only on my family's wireless everything is fine, except I can't connect to the storage device since it has no external connections.
