I'm not an expert, but this may help:
Cameras handle off-loading pictures in two different ways. The more 
fancy cameras have special proprietary protocols for data transfer, and
give the user/owner special control options, but they require specialized
software. Less expensive cameras simply fake a $soft FAT file system and
let you use the file copy functions of your computer to grab the pictures.
Part of digikam is a collection of cloned drivers for the expensive cameras.

It seems to me you (like me) have a less expensive camera which does not
need or use the drivers in digikam. I use 'cp' to copy the images from my
camera into a directory where digikam can find them.
