Webcam Chicony Electronics Co., Ltd

Post by dumischbaenger » 2021/04/08 21:25:03

Hello,

I've installed Centos 8 Stream on my computer. It has a Webcam that is recognized by lsusb as:
04f2:b302 Chicony Electronics Co., Ltd
Cheese and v4l2-ctl do recognize the webcam:
$ /opt/v4l-utils/bin/v4l2-ctl --list-devices
FJ Camera: FJ Camera (usb-0000:00:1a.0-1.4):
/dev/video0
/dev/video1
But every time I try to use the cam it doesn't work and I get errors in dmesg like:
[ 2687.704203] uvcvideo: Failed to resubmit video URB (-19).
Does anybody know what causes this erroneous behavior?

Regards,
Bernhard

Try plugging it into a powered USB hub and see if it works then. By powered I mean one that has an external separate power supply and doesn't draw from the USB port it's plugged into.
CentOS 6 died in November 2020 - migrate to a new version!

CentOS 5 is dead, do not use it.

Unfortunately this is not possible because the cam is built into a laptop computer.
