Unfortunately, I don't remember which version of Calibre stopped recognizing my Kindle, but it was a while back. (Maybe 6 months ago...) I'm running PCLinuxOS and haven't worried about it, since I haven't been trying to send more than a handful of books at a time via emailing via Amazon. Now I have 500+ books to send to my Kindle, and I have no idea how to proceed. At least without Amazon charging me. Any suggestions?
Thanks in advance,
