Eu tenho problema com o uso do modem 3G no Ubuntu. Eu instalei o Ubuntu 14.04 no VirtualBox e usei como sistema operacional convidado. Meu sistema operacional host é o Windows 7. Eu não tenho problema quando compartilhar hosts internet via NAT, mas quando eu estou conectando 3g modem usb embora virtualbox para minha máquina virtual eu não posso criar conexão com a internet. O que estou fazendo?
1) Eu coloco o modem na porta USB e inicio o lsusb
:~$ lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 80ee:0021 VirtualBox USB Tablet

:~$
2) inicie dmesg | cauda
:~$ dmesg | tail

Eu pensei que aqui era um dispositivo como modem detectado, mas quando eu tentei dmesg | grep ZTE :
:~$ dmesg | grep ZTE
