Well, thats unfortunate.
While you were trying, did you get any indication whether you were using
the PTP or non-PTP mode? Did you try both? The reason I ask is that
your model supposedly supports both a "native" (or non-PTP driver)
along with a PTP mode driver:
gphoto2 --list-cameras | grep 'PowerShot A75'
"Canon PowerShot A75"
"Canon PowerShot A75 (PTP mode)"
The former is supposed to provide capture capabilities in addition to
downloads, etc. as reported by:
gphoto2 -a --camera='Canon PowerShot A75 (PTP mode)'
and the latter supposedly provides downloads, uploads, and some other
gphoto2 -a --camera='Canon PowerShot A75'
So its possible that you only tested the inferior of the two available
drivers for that model. But then, I'm an optimist. ;-)
ps - You may have to go into the camera's configuration menu to
turn on/off the PTP support.
