    Trouble with Logitech WebCam, "Failed to open /dev/video0: No such file or directory"

    As in the thread title, I'm having trouble getting this to work in Ubuntu 12.04 LTS.

    I know that this camera has worked in the past, I had a Skype conversation with a friend a little over two years ago on this hardware with a previous release of Ubuntu, but it's been packed away in a box for over a year, and the computer has had an Ubuntu upgrade since.

    Code:
    lsusb
    …snip…
    Bus 001 Device 007: ID 046d:c408 Logitech, Inc. Marble Mouse (4-button)
    Bus 001 Device 008: ID 046d:0991 Logitech, Inc. QuickCam Pro for Notebooks
    So it's identified.

    Code:
    guvcview 
    guvcview 1.5.3

    There is no /dev/video0 device.

    I remember having to create device files, years ago… do I really need to do that these days?

    Even if I open the permissions completely (sudo chmod a+rwx /dev/video0) I get the same "unable to detect video devices on your system" message. Maybe a kernel module is not loaded?
    Code:
    lsmod | grep uvc
    Nothing found… So where is the module?
    Code:
    locate uvc | grep `uname -r`
    /lib/modules/3.2.0-52-generic/kernel/drivers/media/video/uvc
    /usr/src/linux-headers-3.2.0-52-generic/include/linux/uvcvideo.h
    So, try loading one of those, eh?
    Code:
    sudo modprobe uvc
    FATAL: Module uvc not found.
    sudo modprobe uvcvideo
    FATAL: Module uvcvideo not found.
    
    ls -al /lib/modules/3.2.0-52-generic/kernel/drivers/media/video/uvc
    total 8
    drwxr-xr-x  2 root root 4096 Oct 17 17:02 .
    drwxr-xr-x 27 root root 4096 Oct 17 17:02 ..

    Now this is puzzling… because on the Linux UVC driver and tools page, I read the following.

    Linux 2.6.26 and newer includes the Linux UVC driver natively. You will not need to download the driver sources manually unless you want to test a newer version or help with development.
    And I would have expected the presence of the required drivers to have already been verified when I installed cheese, guvcview and all the rest through Synaptic.

    I'll poke around some more, maybe I need to compile and install the drivers myself; I already have some source code for V4L from when I was setting up a DVB-T receiver.

    What's the model of the webcam? Sometimes a "quirk" has to be enabled to get it to run correctly.

    Well the module is there, but not loading.

    I can see that it's not being loaded, but why do you think it is present?

    Re: Trouble with Logitech WebCam, "Failed to open /dev/video0: No such file or direct

    After a lot of thinking about this, I had a look in Syanptic at the files contained in the package linux-image-3.2.0-52-generic. Guess what I saw? That it contained the /lib/modules/3.2.0-52-generic/kernel/drivers/media/video/uvc/uvcvideo.ko driver file.

    I reinstalled the package and I'm about the reboot the system.

    Did you try a different kernel or update the kernel? Looks like in precise-updates the most recent kernel is 3.8.0-32-generic and the module uvcvideo.ko is there:

    I've not tried any other kernels, but I did build new modules to get ny DVB-T receiver to work, and maybe at some point I managed to wipe out the original V4L2 UVC drivers.

    I reinstalled the kernel image, got back the uvcvideo driver and look what I see now.
