I recently upgraded my calibre from 2.40 to 2.50.1 and discovered that I can no longer send any books to my device! The "send to device" menu actually flickers and when you do choose a particular "send to" command there is no effect; the menu is still present (as if you didn't choose anything) and no jobs are started.

After the problem occurred, I went into a different Ubuntu and its calibre 2.40 worked with the same device and Calibre Library, but again once I upgraded to the latest (2.50.1) it stopped working in exactly the same manner. Installing the updated plug-ins after upgrading has no effect.

Has anyone had the same problem?

The software version on my device is 3.19.5761 dated 12/29/2015, and a factory reset made no difference.

Thanks.
