My bad. I sent logs after rolling back to the previous kernel

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

I have the same problem myself too. After updating my creative camera does not work (only the microphone does).

[Stan (stan4611)]

I have the same problem. Kernel 5.4.0-96 is just out. Can somebody confirm if something has changed in 5.4.0-96?

[Piotr (orsei)]

From my experience every single kernel above 5.4.0-91 and 5.13.0-21 doesn't recognize the creative camera. I saw during the boot process that there is a problem of USB device - something unexpected longitude or something (it blinked so fast).... I Hope it is written in the log files. The camera wasn't the cheapest one and there were never problems with it. I tried every single kernel but I reported only 3 of them here in the launpad. Unfortunately nobody gives a .... about it

[Stan (stan4611)]

Thank you for the information. I hope that this bug will be fixed soon, because I need the camera for online work and I can't use Windows :/

Have you found any workarounds other than using older kernel? Maybe some USB settings in BIOS or the OS?

[Piotr (orsei)]

No. It IS kernel-hardware problem. Very singular - creative and derivates. On my laptop (Acer V5-131)the integrated camera works normally despite of the new kernel (-s, because it was many of them I've tried). So it is the new kernel which doesn't recognize specific hardware driver. (With the new kernel I have no folder "/dev/vl4/ which comprise hardlinks to the kernel's driver. It is present with the old one)
My problem is similar to your problem. As a teacher I have to use my camera for my work and I have no MS Windows so without camera I'm done with my work. The solution I took right now is to roll back to the kernel #5.4.0-91 - the last which works with my camera. I froze all updates of the kernel and I can work.
Unfortunately I didn't find another solution :(

[Stan (stan4611)]

I did not find any workaround either. So far I can work with 5.4.0-91. Anyway I hope that this bug will be fixed, but I can see that it is still "Unassigned" with "Undecided" importance, which doesn't lift my hopes.
