Thread: Cannot detect camera with Leap 15.0

  1. #1

    Default Cannot detect camera with Leap 15.0

    Hello everyone!

    I am trying to get my embedded camera to work with my Leap-15.0 installation but without luck until now. I have an embedded HD webcam and mic in my Toshiba Satellite L50-B. I used the Hardware detection module in YaST but I did not see any camera entry.

    I believe that when I used openSUSE-42.1 I had no camera issues, but when I got Leap-42.3 couldn't detect it anymore. I hoped that with Leap-15 I had the problem solved but it didn't. I also tested a Manjaro live session with a different kernel and it was the same, no camera. So, how can I go from here? Any help is greatly appreciated.

    Please run this to see if the webcam is recognized:

    Code:
    dmesg|grep uvc
    Please run this to see if the module is loaded:

    Code:
    lsmod|grep uvc
    This might help as well:

    Code:
    hwinfo --usb
    I assume this is a Chicony webcam. Look in lsusb for it as well.
    I don’t have anything to hide, but I don’t have anything I want to show you either.

    Try:

    Code:
    sudo rmmod uvcvideo
    sudo modprobe uvcvideo
    See if it works then.

    Install guvcview or luvcview and start them to see if the Camera is working.

    Well, no luck. Reloading the uvcvideo module did not seem to work. I tested the camera with guvcview-qt5 and luvcview.
    I ran them in the terminal to display output messages:

    Code:
    guvcview-qt5
    
    GUVCVIEW: couldn't open /home/rodolfo/.config/guvcview2/video0 for read: No such file or directory
    V4L2_CORE: ERROR opening V4L interface: No such file or directory
    GUVCVIEW (2): Guvcview error
             no video device found
    GUVCVIEW (Qt5): fatal error (0 devices detected)
    GUVCVIEW (Qt5): creating error dialog
    Code:
    luvcview

    Video driver: x11
    A window manager is available
    video /dev/video0 
    ERROR opening V4L interface 
    : No such file or directory
    Is this something to do with unsupported drivers?

    Run:

    Code:
    lsusb -v -d  04f2:b446
    If that returns the information about your webcam then you got me.

    We will have seen the kernel recognizes it, loads the module, and it is identified as a USB device.

    No idea why it is not building the /dev/video0 device.

    Hum...I assume it isn't. Also, do:

    Code:
    ls -l /dev/video0

    Did you upgrade, or do a fresh install?

    What desktop are you running?

    Do a:

    Code:
    grep video /etc/group
    Someone with the same desktop will need to tell you what is in their video group. My Leap 15 is running in a VM without a webcam.

    You can try adding your user to the video group, but not sure that will help.

    Well it seems I do not get my camera information with
    lsusb -v -d 04f2:b446

    Also, the file /dev/video0 does not exist in my system.

    I did a fresh openSUSE-Leap-15.0 install and I am using the KDE Plasma desktop. Also adding my user to the video didn't work. I am clueless about this issue...

    Code:
    grep video /etc/group
