Is this bug a regression? Did this issue start happening after a
specific update/upgrade? Was there a prior kernel version where you were
not having this particular problem?

Title:
HP True Vision HD Camera (30c9:008e) - UVC Webcam Detected, Driver
Loaded, but No Image / UVCIOC_CTRL_MAP Errors on Ubuntu 25.04
Status in linux package in Ubuntu:
Incomplete
Bug description:
Problem Description:
My integrated HP True Vision HD Camera (USB ID 30c9:008e) is not producing
any image in applications on Ubuntu 25.04 "Plucky Puffin". While the camera is
detected at the kernel level and device nodes are created, applications either
show a black screen or report errors related to camera control mapping.
Hardware Information:
Laptop Model: (Please insert your specific HP laptop model here, e.g.,
HP Spectre x360, HP Victus, etc. if you know it)
Webcam: Luxvisions Innotech Limited HP True Vision HD Camera
USB ID: 30c9:008e
Ubuntu Version:
Distributor ID: Ubuntu
Description: Ubuntu 25.04
Release: 25.04
Codename: plucky
Symptoms:
Applications like Cheese and Guvcview launch, but display a black
screen where the camera feed should be.
Guvcview repeatedly shows the error: V4L2_CORE: (UVCIOC_CTRL_MAP)
Error: No such file or directory
ffplay can open the /dev/video0 device and identify the video stream
properties (YUY2 640x480 @ 30fps), but the window remains black,
indicating a blank stream from the camera.

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?
