[PROBLEM] Gigabit Lan adapter (USB3) doesn't work

[Nachteule]

You can ignore those warnings, but
there are still issues in XBian-config:

Network is not restarted after change of settings (code is there but is not executed), only settings in /etc/network/interfaces are written.
Seems that this confuses XBian-config completely

Have to investigate this issue next days. For the moment it is easier to modify settings directly in file /etc/network/interfaces and reboot Pi after changes has been done.
