Ubuntu Multimedia :: Camera Could Not Claim USB Device?
Aug 13, 2010
This appears to be a frequently-asked question, but unfortunately all the answers I have been able to find are either outdated or refer to software I am not using. [Edit: this is Lucid upgraded from Karmic on a Dell Dimension 4550] If I plug in my antique little Kodak EZ-200, it appears to be recognised; that is, /var/log/messages says:

*** Error *** An error occurred in the io-library ('Could not claim the USB device'): Could not claim interface 0 (No such file or directory). Make sure no other program or kernel module (such as sdc2xx, stv680, spca50x) is using the device and you have read/write access to the device.
How do I find out what module has claimed the camera, and permanently remove it or prevent it from ever doing so again? Is there some method of telling gphoto2 (or any other camera-handling program) to stamp all over anything else that has laid claim to a device and brute-force its way?
I'm currently running Ubuntu Maverick - 2.6.32-30-generic. I recently bought a Garmin eTrex Vista H, which connects via usb (from my reading, it looks like older versions connected over serial). Well, like so many before me, I can't seem to write to or read from the device via gpsbabel.Originally tried to read anything from the device (I have one waypoint in there) via:
Code:
gpsbabel -i garmin -f usb:
It returned "Found no Garmin USB devices." I then tried turning on the eTrex. Doing the same while locating satellites just does nothing - I have to escape from the command in terminal. Trying again produces the error:

Claim interfaced failed: could not claim interface 0: Device or resource busy
After doing some research, I unblacklisted and then reblacklisted garmin_gps. I also went into
as directed in this . Everything seemed to be correct.I then followed some other advice found here and created the policy under /etc/hal/... Still no luck!
I just got finished installing Ubuntu on 2 computers. I muddled my way thro the panels not installing. Now I would like to hook up a dual mode camera. Vivatar V15 . I know very little about Linux, but as having fought with Microsoft Windows for years I find it refreshing to see Ubuntu. I need to know about device drivers. Ubuntu does not auto detect the camera. The Model of the Camera isV15 Freelance.
I'm using Samsung ES55 digital camera. As you can see in the above , Kingston flash memory is assigned with /dev/sdb disk (system disk is offcourse sda). My openSUSE 11.2 see's the camera , but the device can't be assigned to it. With opensuse 11.0 I did not have this problem, and camera was mounted normally as any other external device via USB.
This device doesn't automount, doesn't show in KDE 4's device notifier, and I can't mount this camera manually because it doesn't appear to get assigned to a device node. Any known solutions? It worked in Slackware 12.2, but not in 13.0 or 13.1.
I switched my laptop from a Windows only PC to a Windows-Linux dual boot. These 2 OS's use all 4 of my primary partitions:On Windows I have a 4.4 GB restore partition which can be used to restore the PC to its initial shipping state.I also have a 28 GB primary windows partition.On Ubuntu I have a 1.8 GB swap drive and a 28 GB ext3 drive for everything else.When I configured the dual boot I intentionally left 30GB dik space unclaimed figuring that if I liked Ubuntu I'd assign it to Ubuntu otherwise I could give it to Windows.
I now know that I love Ubuntu but I'm running out of storage on my disk. I can't delete the Windows partition because I need it for a few programs that don't run on Linux. I'd like to just expand the ext3 partition to take the 30GB that are currently unclaimed.However, I don't see an easy way to do this. When I go to create a partition GParted tells me that I can't have more than 4 primary partitions on a drive, that I need an extended partition.Unfortunately, an extended partition is also a primary partition so I have to delete an existing partition to get this to work. So my question is: Isn't there some way that I can just extend the Ubuntu partition to take advantage of the 30GB unallocated space?
I recently did an upgrade to ubunut 10.04. I have a nikon d70 that I plugged into the computer to download the pictures off of but to my surprise my computer no longer sees the camera. I did a search and found a few threads about USB cameras and skype but nothing about this issue. Is there anyone else having this problem?
Is there a fix for it? So far everything has been working OK with UBUNTU 10.04 I would hate to go back to windows xp only because I am not able to download the pictures from my camera.
I was looking to iphone and i was surprised the quality of such tiny camera.
Is there any alternative camera for my laptop to have similar or much better then the one in iphone? So that i can use it from my laptop, but have very sharp HD quality with maximum megapixel + highest frame per second.
with slackware 13.0 for one user xfce4 hangs and doesn't start..xsession.errors claim it can't open display. It works fine for other users. Also if I access the machine in question as the same user but remotely using remote X (X-terminal on my LAN) it works fine.Sometimes if I wait and count to 30 it comes up but a lot of the features don't work.During the last week have posted this question on the compuserve linux forum and also in the xfce site forum with no solutions.seems there must be something in that user's directory which is hanging it up. I keep the same /home/users directory on a separate partition so when I upgrade for new versions of slackware the /home/users remain the same - I symlink home to that partition so upgrades are somewhat seemless.
I have a creative pc cam 300 that i have been trying to set up as a security camera, on a computer running ubuntu 9.10. I tried installing the spca5xx driver, but i can only find it for old versions of ubuntu and it doesnt work. Does anyone know how to get the driver working?
I have upgraded from Pre-installed Xandros to Ubuntu 9.10 on my Eeepc 701 and my camera is not been detected, even checked the BIOS, where the status is shows as "Enabled"...
I deleted files from my camera (SDHC via USB) which I now want to copy back but I don't know how.
The camera is mounted in ~/.gvfs and the target folder is owned by my user with read/execute permissions. Couldn't change the folders permission.
I tried to mount the camera using 'gksu nautilus', but the camera didn't show up in the side panel. Unfortunately I don't know how to mount the camera from the command line, so I'm stuck.
PS: the only available card reader doesn't recognize SDHC cards, so that's not an option. And no, I won't boot Windows for that task.
My local priest has asked me if I can use my computer skills to stream church services live for people who can't make it to church.I said, sure thing! I thought it would be simple, but the deeper I look into it, the more lost I have become!Here's the tech requirements:
- A camera with good optical zoom and focused on the altar (the camera will be stationed at an unobtrusive point at the back of the church on the choir balcony) - Everything must be wireless (power is available on choir balcony to power the camera). - Sound should be synchronised perfectly with the video (have access to the church PA system - located behind altar) - the internet connection should be able to upload the stream to a virtual server (i.e. with root access) that's accessible to the web with ease. What upload speed would I need? Would 256k be enough? HD video is not required - ..... quality would be great. We can upgrade to HD at a later point in time! - What bandwidth requirement would my server need if say 1000 users were connected? Seeing as they would most likely be locals, would just one stream be sent to the local exchange and that exchange would send out the stream to the 1,000 users, or would each user have to have a dedicated connection to the server? - Say I bought a camcorder with HDMI output, what kind of processing power would I need to convert this to compressed video? (I've got an old Pentium 4 and an AMD64 2.0GHz lying idle in my bedroom and it would be great to make use of 'em instead of chucking 'em on the skip) - I'd like all this to be done so that HTML5 browsers can access the video, resorting to flash if necessary - I'd also like to be able to power down all the hardware with ease: i.e. set a timer. I'm sure ubuntu can do this with ease? What about configuring the camera to zoom in every time it is powered on? Can linux control the zoom on a camcorder? - Am I totally nuts?
I've been having a fit with Ubuntu (even tried updating to the new version). I have a USB camera (1.3mp- 1024x768 ) that I need to observe and capture images with (microphotography). I've downloaded and installed multiple packages, but have not found any way to change the default resolutions for V4l2. The resolution closest to what I need is 1024x816, but the video is torn and unusable. One program, Kamoso, worked fine in 640x480 mode, but as soon as I upgraded to Ubuntu 10, it went to the higher resolution (1024x816) which doesn't work right.
Is there some way to force v4l2 into a 1024x768 mode? The camera is a Tucsen 1.3mp microscope camera. I've emailed the company for more information and to see if they would email me the software/drivers (I lost the driver disk in a fire), but nothing so far from them.
The programs I've installed and tried: Camorama, Kamoso, Xsane, Cheese, VLC media player, v4l2ctrl, v4l2ucp, v4lctl, v4l-info. Camorama doesn't work, Kamoso- you couldn't change resolutions (ditto for Xsane), Cheese - I can change resolutions, but they have these crazy values that don't work, VLC media I cannot change either. I'm supposed to be able to use v4l2ucp to change settings, but I don't get the screen that the preview for the program (in Ubuntu Software) showed.
Previously I could plug my EOS 20D into the USB and f-spot would pop up and let me import photos. This was on 9.10. The camera is fine, it still does exactly what it did on the machine next to me which is still running 9 (or 8, I forget).
having a problem getting my web camera recognised at start up. when i boot my machine and run , cheese or skype no camera , if i unplug it and plug it back in it works fine . Till i shut down and boot up again .
I bought a USB to firewire cable to use with a DV camera, but I don't know what to do now. Do I need to enable firewire drivers, or is there something else I should do? I know I should read the manual.
I use F-spot and Shotwell to extract photos AND videos that I made with my Canon EOS 500 or my Lumix.Actually the pics are extracted correcly but the videos are just consider as a pic and the pic is the first pic of the video.Is there any F-spot equivalent that extract everything from the camera?
I have a Panasonic DVCPRO HD camera with a Firewire output. I'd like to take the video footage off of the camera and put it into my Ubuntu (Studio, 10.04) machine. Unfortunately, neither my Ubuntu machine nor the camera seem to recognize a connection with each other.
I've only used this camera like this with Mac OSX, in which I press a button a couple folders pop up with everything in them which I can then digitize in Final Cut Pro. I'd prefer being able to use my Ubuntu setup with Open Source Software to view and edit this footage.
how to get ubuntu and this camera to talk to each other and play nice?
I am a Ubuntu newbie (installed Ubuntu 10.04 LTS last week) with a camera problem. My Canon SD300 won't automount when I attach it by usb cable. It is visible to F-Spot and I can import pictures, it just doesn't automount. I saw other posts where no usb automounts were occurring. Not my problem. Memory sticks and external hard drives automount just fine. Only the camera is a problem child.
It is a Microdia PC Camera (SN9C120). Using the command lsusb, I can see it listed in the USB listing and cheese/skype seems to detect the fact that I have a webcam, yet all I get is a blank screen and the mic doesn't work. I have tried to install the SN9C20x USB 2.0 Webcam Driver but this has not solved the problem. Unfortunately, I am not sure whether I installed it correctly and it doesn't work, or whether I just installed it incorrectly as I am a bit of a Linux novice.
