Wired Ethernet su Intel Edison

Come prova ho provato a connettere via cavo Ethernet la Edison utilizzando un dongle USB-Ethernet

Il primo tentativo (ricordarsi di spostare il selettore verso la porta USB standard per attivarla) , utilizzando un dongle Lenovo USB 3 che usa il modulo cdc_ether, non e' andato a buon fine perche' il modulo non era riconosciuto dal kernel

Successivamente ho provato con un vecchio dongle USB-Ethernet di Apple che utilizza il modulo Asix  AX 88772 che e' stato immediatamente riconosciuto

Peraltro il dispositivo ha assunto direttamente l'IP da DHCP

A questo puo' essere comodo disabilitare la connessione WiFi con i seguenti comandi

systemctl start connman
systemctl enable connman
connmnanctl
connmanctl> disable wifi
