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.
Thank you.

Thanks for the confirmation, I'm closing the bug then.
