If yes, could you give that information?

yes it worked in earlier versions of opensuse, for Leap 15.1, and Tumbleweed for last year November.

Do you still have the old working kernel?  It's too old, so it's no longer in the TW history repo.

Or, maybe you can try to install Leap 15.1 kernel onto your TW system.  (You can install manually via zypper install --oldpackage option).
At least, we need to compare with the working state.

If it was possible for you to tell me the version, I can try at least.
Comment 7 Takashi Iwai 2020-07-20 16:33:46 UTC 
You can try just installing the latest openSUSE Leap 15.1 kernel, e.g. from OBS Kernel:openSUSE-15.1 repo
  http://download.opensuse.org/repositories/Kernel:/openSUSE-15.1/standard/

Grab kernel-default.rpm, and install it manually via zypper
  zypper in --oldpackage kernel-default-4.12*.rpm

You might need to add --nodeps option for ignoring the kernel-firmware dependency.  Then reboot with that kernel (go "Advanced menu" in GRUB menu and choose it).

Similarly, try Leap 15.2 kernel from
    http://download.opensuse.org/repositories/Kernel:/openSUSE-15.2/standard/
too

Installed 15.2 with kernel 5.3.18-lp152.16-default, doesn't work with it either.
Also a few days back in Tumbleweed with kernel 5.7.7.1-default, the webcam was working perfectly fine. Now suddenly, even without an update it stopped working
Comment 9 Takashi Iwai 2020-08-16 08:02:43 UTC 
Weird.  I guess the best would be to report this to upstream.
Care to open a bug report for the upstream, e.g. bugzilla.kernel.org?
Feel free to put me (tiwai@suse.de) to Cc there.

and now it's working fine again, suddenly. Do you wanna have a look at the logs?

The rapid cycles of disconnect/connect seem to point to a USB host controller or USB core issue. If you open a bug upstream, I would recommend filing it with USB, not media or UVC.

I have already filed a bug, would you mind if I add to you to the CC list?
Comment 13 Erico Mendonca 2020-09-28 19:41:18 UTC 
I'm getting similar problems with a couple of generic off-brand UVC cameras that worked before Leap 15.2:

This is on kernel 5.3.18-lp152.41-default. It worked up to the latest 15.1 kernel. Could this be related? I can get a detailed lsusb for these devices if needed.

Could you identify the kernel version which still works?
Comment 15 Erico Mendonca 2020-10-02 22:35:39 UTC 
That would be the latest 15SP1 kernel, 4.12.14-lp151.28.67-default.

Do you need any logs?
Comment 16 Takashi Iwai 2020-10-05 12:54:37 UTC 
Unfortunately, the upstream dev requested git bisection, so we need someone doing that...
Comment 17 Miroslav Beneš 2022-01-07 12:27:50 UTC 
...and it has not happened yet, I suppose.

Aman, Erico, is the issue still present with the latest TW kernel? It has been a while.
