I've tried both the Amazon cables listed. Bingfu showed no camera, the other shows the weird cable icon. Couldn't find any locally to try. The bingfu may actually be bad as it's showing open when I ohm it. I requested a replacement and while I wait I'm looking for yet another cable.
I just can't fathom that given the pinouts matching 19-21 it would be a programming issues. Who knows? The cheapest, fastest, thing for me to try is new cables. With it showing two different icons on two different cables I'm still banking on bad luck on a cheap part.
