The ebook reader is detected fine, with the internal and external memory separate, it does deposit file in the right folder. Yes, i've been able to use Calibre with it by selecting the default profil and changing the way calibre put file in that folder.
By default, it use a structure as:
{author_sort}/{title} - {authors}
But the Samsung does not support folder in the ..\Books\ Files must be directly put in. Of course, i can do it manually and get calibre work just by tweaking that.
I just though that it might be better for Calibre to get a specific profil for the Samsung E60 for people who don't know how to deal with it.
Since in France it's actually 49€ for that reader... You got a huge chance to get load of users
Anyway, my point was just to help a bit Calibre
