(runtime output) ... Troubleshooting Steps Attempted: Confirmed uvcvideo module is loaded and device nodes (/dev/video0, /dev/video1) exist. Attempted to use guvcview and cheese, both resulting in no image and guvcview showing UVCIOC_CTRL_MAP errors. Attempted to load uvcvideo module with quirks=128 (via sudo modprobe -r uvcvideo then sudo modprobe uvcvideo quirks=128), but this did not resolve the issue. Confirmed ipu6-drivers DKMS module is installed, but later determined the camera is a USB UVC device, not an Intel MIPI IPU6 camera. Attempted to use mpv and ffplay to directly stream from /dev/video0 with specified formats (MJPEG, YUYV) and resolutions. ffplay successfully opened the device and identified the stream, but displayed a black screen. Request: Given that the camera is detected, the uvcvideo driver is loaded, and device nodes are created, but applications fail to get a visual stream and guvcview reports UVCIOC_CTRL_MAP errors, it appears this specific UVC webcam (ID 30c9:008e) may require a specific uvcvideo quirk or a driver patch for proper initialization and control mapping. Could you please investigate if a known quirk exists for this device ID, or if this is a new issue requiring a driver update?
