I have a 6" EZ Reader, and was given a gift card to the Sony bookstore. I dutifully downloaded ad installed their software, registered my card, and bought couple of books. All of this went fine. My problem is that the software/bookstore does not recognize my reader as a reader--it sees it as an unknown drive on the computer. So I can't transfer my books to my reader. Since the Sony software sees the reader as a drive, it seems that all connections, cables, etc are OK. I followed the directions in the Sony help files for registering my device several times, but no luck. What am I missing that is preventing the software from seeing that it's a "tethered device?"
