Update:
Ich habe die Webcam nun noch via ein USB Hub angeschlossen.
Wenn ich via ssh versuche den solid-state-switch zu schalten
mittels Python (nicht brickv) dann erhalte ich diesen Fehler:
Traceback (most recent call last):
File "solidState_OFF.py", line 20, in <module>

Der Fehler scheint immer erst nach einer Weile aufzutreten, denn wenn ich power-cycle dann geht es zuerst ein paar mal.
