R.. GitHub STOP HELPING ICE
<p>I try to set up the focus of my Logitech C920 in OctoPi. I follow several guides, which all propose to set the command <code>sudo v412-ctl --set-ctrl=focus_auto=0</code> by SSH'ing OctoPrint.
I always receive the answer in SSH, that <code>v412-ctl command not found</code>.
What's wrong?</p>
