Bug#1123619: /usr/share/bug/linux-image-6.17.11+deb14-amd64/presubj: Regression: IMC Networks USB2.0 UVC 2M WebCam found but unusable (was ok in image 6.17.9)
Hi Salvatore,
Sorry for top posting. Quickly, I am almost sure now that it is a hardware failure from my laptop. Even using the old kernel now works only from time to time. First I thought a bad state could survive across reboot but now i just think it depends on the heat of the laptop... Last time i even had a BIOS error before to boot. This cannot be related to the kernel.
Thank you for the time you took to guide me, sorry for the noise. Please close this bugreport.
Best regards,
Benoît
