I've been using Calibre to convert old ebooks for my iPad for some time and it works great. For Fathers Day my daughter bought me a Kindle so I converted some books to Mobi and put them on the Kindle. But now Calibre won't detect my iPad or iPod, which is really inconvenient. I've tried deleting Calibre and reinstalling as well as restarting the initial setup, no effect. Any ideas out there?
