Kernel log with uvc-trace patch applied

I'm on 6.0.2 and seemingly get this even more frequently with good cable and no
extra adapters. So I patched 6.0.2 with uvc-trace above and reproduced it
within a few minutes.

USB seems to reset, often camera stops or freezes in the browser, but the light
on the camera itself remains on. Sometimes I can enable/disable/enable camera
for it to reboot, but the last time I did that in the log I got null pointer
de-reference again.

Please let me know if there is any other information I can provide and what
could be the root cause of this annoying behavior.
