Hi,
I am trying to run webcam on laptop under Fedora 21 with linux kernel
3.17.6. I had problem with my integrated webcam (13d3:5130) so I decided
to buy external webcam (0c45:6341 Microdia Defender G-Lens 2577 HD720p
Camera). However, symptoms were the same.
When I run some webcam viewer (cheese), it takes some time until a first
picture is shown and it is refreshed again after several minutes. I have
observed that the picture is refreshed when load of CPU is high. When I
tried to run (for increase load of CPU)
$ while true; do echo 1; done
so the webcam worked well.
dmesg when I connected the external webcam
