Ipad 4, Marvin and Calibre

[ksteiner]

Okay, I swapped my iPad around - stupid thing to do and now Marvin, calibre, my laptop and iPad do not like each other any more!

My iPad 4 celluar and wifi runs on iOS9.2. When I connected the device to the laptop and tried to run calibre and the marvin get book option, the device did not show up.

Among other things I tried deinstalling and re-installing the plugin but everytime I reached the step to customise the plugin "iOS reader applications (1.4.7.0.0) by Wulf C. Krueger Communicate with Apple iOS reader applications" to set Marvin as preferred reader application, I cannot complete the step and get the following error message

calibre, version 2.46.0

I also tried to debug device detection and it did not work

Any bright ideas?

Thanks
