Thread: UVC Camera shuts off after 3 seconds in Tumbleweed

  1. #1

    Default UVC Camera shuts off after 3 seconds in Tumbleweed

    Hello,

    I'm trying to use a basic USB-powered UVC camera (think generic GoPro) as a webcam in fully-updated Tumbleweed 20210221. When I set the camera in Webcam mode, it stays on for exactly 3 seconds, then stops. This behavior happens only on my Tumbleweed machine but not on a Windows 10 laptop; the camera stays on continuously in Webcam mode on Windows as it is designed to do.

    Google tells me it may be a kernel issue but I'd like to get your take on it.

    Here's the system log from the time the Webcam is activated until the time it stops:
    Code:

    Default AW: UVC Camera shuts off after 3 seconds in Tumbleweed

    The BugZilla report certainly sounds like the issue I'm experiencing, but I can't understand the action that I need to take. They mention it is fixed with a particular patch, but how could I tell if that patch is in the current Tumbleweed kernel, or when it might be rolled out?

    Are there any other avenues to pursue with remediating this problem?

    Hi
    Unlikely since it's still active... Open an openSUSE Bug report against the kernel at openSUSE:Submitting bug reports - openSUSE and point to the kernel bug, they might include or know it's status...
