I just managed to solve my problem. 😀

So I want to share my solution:  
After a bit of research yesterday I found out, that since the last MacOS Update to Sierra Apple added their own FTDI driver to the System.

So the solution was, to remove the other two FTDI-Drivers I had installed from the kernel extensions.  
And now it connects / disconnects without a single problem and without a restart 👍

I am pretty happy

Here are the links that lead me to the solution:
