I've added the stretch-backports repos and installed the new kernel and

But it doesn't seem to have sorted much out. The camera gets recognised
for a few minutes and then it stops.
I just did a search in google for TP 130
https://wiki.debian.org/InstallingDebianOn/Thinkpad/Edge-E130/wheezy
http://linux-hardware.org/index.php?id=usb:5986-0299
It looks like it is supported since wheezy and reported to be recognized up
to kernel 5.10. If it does not work - either there is something else or a
regression. Something else could be udev or some other subsystem that
messes up.

$ sudo uvcdynctrl -l
