Comment 2 Takashi Iwai 2020-08-18 08:08:56 UTC
Lauren suggested in the opensuse bugzilla above:
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.

Let's reassign to USB people.
Comment 3 Alan Stern 2020-08-18 15:22:43 UTC
The opensuse bug report says that the problem comes and goes, and it affects old kernel versions as well as the current one.  This sounds like a hardware problem, not a software issue.
Comment 4 Aman Vaishya 2020-08-18 15:43:19 UTC
I am also using openSuse 15.1 alongside the tumbleweed verison, this issue doesn't seem to appear there.
Comment 5 Alan Stern 2020-08-18 18:47:44 UTC
If you have two different kernel versions, and the device reliably works under one and reliably fails under the other, you should be able to use bisection to pinpoint the single change in the kernel which was responsible for the change in behavior.

If you aren't able to carry out a bisection yourself, you may get help from the opensuse people.
