If I use my Canon G9 with an 16GB SD card II can easily import images in
But if I use the G9 with a 32GB SD card then it works only until the
SD-Card is less then 50% full. If it is more full then show the Cameradisplay
"comunication error" if I would like to start an import.
If I use the camera with the same 32GB SD card on Windows I can always import
images into the Canon software.
I use the camera connected via USB in PTP mode to my computer.
Have a look for the digikam bugreport
