The camera is often not detected, or the video feed is unstable, frequently cutting out with no clear error messages in standard system logs. Restarting the pipewire.service (user-level) sometimes temporarily resolves the "no camera" issue, allowing the camera to be used. However, the video quality is often limited to very low resolutions (e.g., 180p), and even at these low resolutions, the video can be choppy or exhibit intermittent issues. Attempting to use higher resolutions consistently leads to the video feed cutting out entirely. Kernel logs (journalctl -k -f | grep uvcvideo) show "Failed to resubmit video URB (-19)" errors, indicating a problem with USB communication to the webcam. Troubleshooting steps taken include: Trying various uvcvideo quirks via modprobe and /etc/modprobe.d/uvcvideo.conf. The quirk options uvcvideo quirks=0x00000080 (UVC_QUIRK_FIX_BANDWIDTH) seems to provide the most stable experience, allowing video at very low resolutions (180p) in both Google Meet and Zoom, although Zoom is choppier. Higher resolutions remain unusable. Investigating USB power management using powertop, which showed the webcam's autosuspend was already set to "Good." Restarting the pipewire service. Testing with a command-line webcam application (snapshot), which also crashed. Checking pipewire logs (journalctl -u pipewire.service), which showed errors related to VIDIOC_STREAMON, VIDIOC_STREAMOFF, and VIDIOC_REQBUFS with "No such device" errors for /dev/video1. The issue was also present in a Timeshift restore to Ubuntu 22.04 from a point where the camera was previously working, suggesting a potential regression or persistent configuration issue. The problem started around April 19, 2025.
