The 40D is an old camera and I'm not sure if it will work with qDD. Did you try connecting it directly with USB to your OSX? Does that work?

[aifer2007]

Thank you.

Yes， 40D works on my OSX. And, I have resolved the problem. When the 40D is connected, the raspbian OS mounts it as a disk volume auto. I just unmount the 40D volume , then qDD works.

Glad it worked.

Worked for me too. Thanks for the tip !

For anyone having the same issue and if you don't see the mounted volume, check and disable the auto mount option of raspbian anyway. It should be in the file browser preferences.

Then reboot and try again.
