In a plot twist, I discovered that the original camera has already had
this quirk applied 15 years ago. So my ID squatter gets the quirk too.
(I think it's a squatter, the old chip was USB 2.0 and this is USB 3.0).
Not sure why I believed otherwise and used to set it with modprobe.
Maybe I noticed the excessive bandwdith requests made by buggy quirk,
then force-enabled the quirk hoping it will solve them, then fixed the
quirk to actually get it right.
Michal
