Vor dem Update funktionierte es einwandfrei, erst da nach kam es zu dem Serial Port Problem.
Ich bin nicht sehr fit was Ubuntu angeht, aber ich hoffe das ihr mit bitte weiter helfen könnt. [Before the update it worked perfectly, only after it came to the Serial Port problem.
I'm not very fit for Ubuntu, but I hope you can help with that.]
