My old kindle (which I no longer have) worked fine with calibre on this computer. Santa brought me a new kindle paperwhite with firmware version 5.10.1.3
I use calibre 2.55.0 on Linux mint 18.
First of all I went through all steps in the post
My device is not detected by calibre
The kindle is detected by my OS and I can browse through its folders. Nevertheless the device icon does not show up in calibre and I can not send ebooks to it.
No other device is connected and I tried different USB ports. The ignored devices list is empty and all installed kindle plugins are active. I restarted kindle and calibre.
Here is the debug device detection log:

lsusb shows a Labl26 device that seems to be not detected by calibre and that is only listed when my kindle is connected:
