It identifies as: [34367.545510] uvcvideo: Found UVC 1.00 device Android (1f3a:100e) Everything was working fine with openSUSE Leap 15.2 and Kernel 5.3.18-lp152.47-default (RPM kernel-default-5.3.18-lp152.47.2.x86_64) and earlier versions. After updating to kernel-default-5.3.18-lp152.50.1.x86_64 the webcam stopped working. This is also true for later Kernel versions. With Kernel 5.3.18-lp152.47-default I can capture the videostream, e.g. via: --- snip --- user@box:~> luvcview -d /dev/video2 luvcview version 0.2.1 Video driver: x11 A window manager is available video /dev/video2 format asked unavailable get width 1280 height 720 Clean Up done Quit --- snap --- With Kernel 5.3.18-lp152.50-default I get no stream and this error: --- snip --- user@box:~> luvcview -d /dev/video2 luvcview version 0.2.1 Video driver: x11 A window manager is available video /dev/video2 Unable to set format: 22. Init v4L2 failed !! exit fatal --- snap --- On a related note: In order for the device to work I have to disable USB autosuspend (as suggested under https://www.ideasonboard.org/uvc/faq/): --- snip --- echo -1 > /sys/module/usbcore/parameters/autosuspend --- snap --- -- You are receiving this mail because: You are on the CC list for the bug.
