when downloading a DRM PDF from Kobo I do not appear to receive any serial number, yet when I try to register the book w/ Adobe Digital Editions, I am asked for a serial number. Where is the serial number?
Is a Samsung Note 10.1 supported by Digital Editions (via Universal Book Reader app)? I don't see it registering on Adobe Digital Editions when linking devices via USB, yet do see the SS Note 10.1 in your list of supported devices in your blog
