Answer 1

Executar no terminal

sudo -H gedit /lib/udev/rules.d/40-usb_modeswitch.rules

e adicione uma linha ao arquivo

ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1505", RUN+="usb_modeswitch '%b/%k'"

Em seguida, execute

sudo -H gedit /etc/usb_modeswitch.d/12d1:1505

e cole este texto no editor

 TargetVendor= 0x12d1
 TargetProduct= 0x1505
 MessageContent="55534243123456780000000000000011062000000100000000000000000000"

Salve o arquivo.

Desconecte o modem e conecte-o novamente. Em cerca de 20 segundos, tente criar uma conexão.
