Hello
I encountered the same problem and I did not manage to solve it despite the explanations provided here.
I typed the command:  ls /dev/tty*
I read a lot of /dev/tty , /dev/tty0, /dev/tty1....... but no /dev/ttyUSB0
I listed the ports without connected the USB cable and I saw at the end of the list: /dev/ttyAMA0
when i connected the USB and typed ls /dev/tty* and i saw at the end of list a new port: /dev/ttyACM0
i modified the cumulus.ini file with:

Code:

[Station]
Type=0
Model=WeatherDuinoPro2
Port=/dev/ttyACM0
UseDavisLoop2=0
ComportName=/dev/ttyACM0

relaunch the command: sudo mono CumulusMX.exe
now the station is connected.

This is another solution for those who can not find the USB0 port
