when I type udevadm info -q all -n /dev/video0 I get:
IMHO one should start with this, the most important fact. So that people who try to help do not have to read through all of a post before finding it. After wjch they can start reading anew with this fact available in the interpreting of what they read.
And please, when you copy/paste between CODE tags, do make the mouse sweep a bit larger. And let it inclusd the prompt, the command, the output (the only part you already put there) and the next prompt. Very easy. And it saves you the action of making things bold and the writing of “the poutput of”. We will see that ourselves then. And it will provide more information then the story telling.
the 1st question I would ask myself if I had the above error, is do I have the necessary v4l apps installed ?
So I would then check to see what v4l apps I have installed, and also check what was available for installation.
So that is the webcam. I would ask myself, what driver is the webcam using ? Can you tell us the driver ? The uvc driver is quite common, but when I look at the openSUSE webcam page under the list of supported GNU/Linux webcams I don’t see that webcam listed for uvc nor gspca drivers.
So I would look inside dmesg and/or /var/log/messages to see if I could determine the driver.
The output of " udevadm info -q all -n /dev/video0 " is not encouraging.
