Package: linux-image-amd64 Version: 6.12.74-2 Severity: important X-Debbugs-Cc: [email protected]
Dear Maintainer, System: Debian Trixie (KDE Plasma) Kernel: 6.12.74+deb13+1-amd64 Device: Internal HP Wide Vision HD Camera (USB ID: 30c9:0069) Issue: The internal webcam is detected but fails to stream video. Details: - /dev/video0 and /dev/video1 are present - v4l2-ctl shows MJPG and YUYV formats correctly - Applications such as Cheese, ffplay, and Signal show a black screen - Camera starts but immediately disconnects Kernel logs show repeated errors: uvcvideo: Failed to resubmit video URB (-19) This is followed by repeated USB device reinitialization. libcamera: - cam -l detects the camera correctly - cam -c1 opens the camera but no preview/output is shown Troubleshooting performed: - Disabled USB autosuspend - Reloaded uvcvideo with quirks - Forced MJPEG and YUYV formats - Reduced resolution and FPS - Tested multiple applications - Issue persists in all cases Result: Camera stream fails immediately after initialization and repeatedly disconnects. Conclusion: This appears to be a regression in the uvcvideo driver or kernel 6.12 affecting this webcam. Expected behavior: The camera should stream video normally via V4L2 and libcamera.
