Comment # 13 on bug 1173448 from Erico Mendonca

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.
