  1. Hi,
    once the user has many ebooks listed in the device library, say few hundreds, it is pretty difficult to go thru the list to find the book one needs. Does the library have a search functionality to help finding or filtering books by (part of) author name or by (part of) book title ?


    1. Hello Daniel,
      Thanks for your message. If you have a large library, we recommend you use folders to organise it and then activate the Folder View via the menu. This will make it much easier to navigate. There is no search function in the library at this time. If you like, you can make feature requests directly by using the contact form on our site.
      Best regards,

    1. Hello Gospod,
      support for djvu is not planned at this time. It’s a format which is not really adapted to reading on a small screen, since it is not reflowable. We recommend you choose epub format instead.

  2. Hi!

    Disaster…the device will connect/disconnect on my MacBook Pro Lion OS…it is never found by ADE. On my windows machine, windows fails to install any device driver for the unit…it is not found by ADE there either!!

    Seriously…I payed 200 euros for the device/cover/wall charger, and it does not even connect to my computers?!


  3. Hi
    I see that you are rapidly upgrading the firmware. Nonetheless I still I have big problems in USB connection. Acually I am unable to see the reader through my Windows 7 system. It is the case to send the device for a repair?
    Thanks Francesco


  4. Hello Simone,

    Any news on this problem from Bookeen support ???

    I also faced some times this problem of automatic start up when i put my odyssey in stand by mode.


  5. Hi Manolis,
    I’ve written to support more than 1 week ago, but no answers yet.
    BTW with the last firmware (v1485) I find the odyssey shutted down instead of “on” discharging the battery.
