[Kernel-packages] [Bug 1881757] Re: webcam is detected but not working with kernel 5.4.0.33
i don't think this is solved. my monitor webcam was working fine in April/May. i use no special drivers, it is a desktop monitor with effectively a USB hub and webcam built in (so using the standard plug and play UVCVIDEO drivers). It has now stopped working. Doesnt show up in Cheese or in Guvcview. if i run dmesg i get: [ 7116.802582] usb 2-5.1: Product: Monitor Webcam [ 7116.802586] usb 2-5.1: Manufacturer: OmniVision Technologies, Inc.538-2640-09.07.24.1 [ 7116.804179] uvcvideo: Found UVC 1.00 device Monitor Webcam (05a9:2649) [ 7116.805930] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported.

[ 7116.806306] uvcvideo: Failed to initialize the device (-5). physically unplugging and replugging its usb doesnt help. neither does rmmod uvcvideo and modprobe uvcvideo. Weirdly, unplugging from my desktop's own USB slots - which are usb 2 (EHCI) - and moving the monitor usb cable to an empty usb 3.0 (xHCI) slot fixed the issue! So i am back in business, but i believe whatever issue keeps popping up (for different webcams every few kernel releases), is still there... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed in Ubuntu. https://bugs.launchpad.net/bugs/1881757 Title: webcam is detected but not working with kernel 5.4.0.33 Status in linux-signed package in Ubuntu: Fix Released Bug description: webcam is detected not working under kernel 5.4.0.33 and 5.4.0.31 .
