Here comes the strange part of the whole procedure:

My camera had allready lots of photos inside the flash memory card, but
I could not read them with my eCS system and your drivers.
I read in the newsgroups, that this is something to do with the
formatting of the flash memory card. I reformatted the card using
cameras own format-command and VOILA' after this the eCS was able to see
the flash card as a removable disk. Flash memory card with all the
photos is functioning perfectly after this reformat.

So one just wonders what kind of formatting there was in the first place
in the memory card. Anyway everything seems to work now.
