Canon PowerShot SD750 Digital ELPH compatibility with Digikam

goodirishstock · 06-22-2007, 07:45 PM

As usual I can't seem to get DigiKam to recognize my new digital camera.. this is my third such problem with different cameras. Luckily I have a card reader on my HP Printer that i was able to use to get DigiKam to take the images from the camera to my harddrive. There has to be a more automated way of doing this !!! I run Debian for DigiKam Version 0.9.0 beta3 using KDE 3.5.5. Anyone one have any suggestions?.. Appreciated any help you might send my way

can you describe what exactly you have tried to make digikam recognise the cam ? Just asking because no canon cam I ever had here made problems. What does lsusb say when you plug in the cam ? Did you try to manually add the cam in the control center (that's what digikam refers to as it's a kde application) ?

Same problem for me
Cannon PowerShot SD750
I tried several canon drivers (sd700, ixus750) and USB PTP mode. No luck with autodetect.

I found this

Quote:

Since I think libgpio uses direct port IO, you have to be root, or the
program needs suid root. In /usr/local/bin, do
chmod u+s gphoto2

for me (Gentoo) it was in /usr/bin.
this allowed non-root to use gphoto2 and access the camera:

cat ~/.gphoto/settings
gphoto2=model=USB PTP Class Camera
gphoto2=port=usb:

digikam is still not working though...
will post more if I find the problem with digikam

I also looked at permissions and group (discussed in this thread).
My user (dsp) can 'head' the device (/proc/bus/usb/001/003 in this case), so permissions don't seem to be the problem, although since it works as root it does seem to be a permission problem...
