Since I'm on Linux Mint, I got the source of gtk-v4l, went through the

But unfortunately, the focus control does not show up. Almost certainly
due to non-standard camera internals. I rather expected this from the
uvcdynctrl output and the guvcview program.

My guess is that some custom patching needed. Device is quite usable,
just not perfect.

You could try v4l2-ctl from the v4l-utils package, for example with my random cheapo MS webcam, it shows for --list-ctrls option:

focus_absolute (int) : min=0 max=40 step=1 default=0 value=0 flags=inactive
  focus_auto (bool) : default=0 value=1

If it's listed there, you could control it with:

  v4l2-ctl --set-ctrl=focus_auto=1 -d /dev/whatever

Maybe you'll get lucky.
