I have a kobo touch. Download to Ade via Kobo books. Most are not a problem. I can also drag and drop books from My Digital Editions but some of them just say 'this file's format is not currently supported"
Both the eReader and the computer are authorised to Ade.
I have plugged in the USB and transfer books from Ade as well as from the Kobo desktop app but some of these same books seem to able to be read on the computer only, I also transfer books through wifi connection .
I don't understand, I thought Ade supported epub books as well as DRM.
I guess I am doing something wrong, but haven't figured it out yet.
