Comment on New Kindle e-readers no longer appear on computers

  In short, no.

  What’s changed here is now the Kindle and PC will actively communicate with each other during file transfers with MTP instead of the Kindle “pretending” to be a USB flash drive with USB mass storage. There are some important trade-off that come with the switch to MTP but nothing that will stop you from transferring ebooks to or from a computer.

    Nice one thanks for clarifying. Sounds like a relatively minor change?

      Pretty minor as long as your computer’s OS supports MTP, which most do, except for MacOS. If you’re a Mac user, you’ll need 3rd party software like Calibre or Android File Transfer for it to show up, but if you’re the kind of person who’s transferring books to and from your Kindle over USB, you’re probably already using Calibre anyway.

    Yeah, until they do this:

    Media Transfer Protocol (MTP) over USB Mapping

    The MTP extension defined in this section provides a mapping of WMDRM: Network Devices Protocol messages to the Media Transfer Protocol (MTP). The WMDRM: Network Devices Protocol extension to MTP defines operations that enable DRM-protected content to be securely transmitted from the transmitter to the receiver.

      The Kindle doesn’t use Windows Media DRM for its DRM protected ebooks, they use Amazon’s own DRM. Even if they did use WMDRM though, this is just an extension MTP that would enable it to be used for streaming WMDRM content. It “provides a mapping of WMDRM: Network Devices Protocol messages to the Media Transfer Protocol (MTP)” and that’s necessary because MTP would otherwise not provide the data necessary for for the DRM protected content to play.

      There’s still nothing here that would prevent you from copying your own “legitimately obtained” epub files or Amazon-encrypted AZW files to or from your PC.

      I do see this article was the first result when I searched “MTP DRM” on Google though 😉

        First step is to make it able to transfer DRM, second is to implement it only allowing DRM.

        I don’t think they would invest money into something that they wouldn’t have to change if they didn’t try to get control over your data transfers, and the only logical reason I can see is DRM. They’re expecting a return of investment for every penny they spend.

        USB protocol isn’t broken, so why would they change it?

        What would be reasons that make this investment worthwhile?
