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.

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.

I am also using openSuse 15.1 alongside the tumbleweed verison, this issue
doesn't seem to appear there.

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.
