Not sure the best place to share this but this seems like a good bet ?

Nice find, but I don't think it belongs in the chdkptp thread.
Don't forget what the H stands for.

Thanks for moving it.  Reading the code and articles,  it seems to depend somewhat on earlier Canon P&S cameras where the PTP code had a lot more functionality.  Does that make sense?

So a "refresh" to make use of the things CHDK adds to the camera side of PTP might be in order?

canon stopped supporting remote control / shooting functionality in most of their P&S a long time ago.

The library doesn't seem to have any specific support for CHDK. Someone made a comment in 2012 about adding CHDK support, but from a brief look it doesn't seem like it went anywhere.

People should be able to use this library to call CHDK PTP extension functions without too much trouble. Someone could build a higher level CHDK library on that if they wanted.

You can now get a few nice USB host "shields" for about $20 to attach to a $10 Arduino card.   Makes for some interesting "advanced" USB remote possibilities.



(Although the guy who took this picture did not see a need to solder the two boards together  :P )
