Canon EOS USB communication protocol

Post by Oki » Sat Dec 05, 2020 10:38 am

Hello everyone,

is there some documentation to Canon EOS USB communication protocol available? I mean something like list of commands with variables and explanations. I only found some bits to old non-dslr cameras, but there certainly must be something if open-source apps like digiCamControl keep appearing :) I was even able to find EF communication protocol documented nicely, but USB-camera communication is still mystery for me. Thank you!

No official Canon MTP protocol documentation, even digiCamControl use the official sdk for it. You can find some info about it, but mostly are result of reverse engineering
