/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/5p, 480M
    |__ Port 2: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
        |__ Port 4: Dev 4, If 1, Class=Human Interface Device, Driver=usbhid, 12M
        |__ Port 4: Dev 4, If 0, Class=Human Interface Device, Driver=usbhid, 12M
    |__ Port 3: Dev 3, If 0, Class=Hub, Driver=hub/4p, 12M

        |__ Port 1: Dev 5, If 4, Class=Vendor Specific Class, Driver=GobiNet_Neoway, 12M

3、4G Modem Ethernet 设备确认？ （eth0 or eth1)

root@nano-tw:~# ifconfig eth0
eth0: flags=4291<UP,BROADCAST,RUNNING,NOARP,MULTICAST>  mtu 1500
        inet 10.4.201.79  netmask 255.255.255.224  broadcast 10.4.201.95
        ether aa:69:b8:ed:86:b4  txqueuelen 1000  (Ethernet)
        RX packets 14  bytes 2164 (2.1 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 75  bytes 8905 (8.9 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

root@nano-tw:~# ifconfig eth1
eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.100  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::3309:6ad3:bb45:c1b4  prefixlen 64  scopeid 0x20<link>

        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 528  bytes 52199 (52.1 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 149  base 0xe000  

4、GobiNet 拨号确认？

root@nano-tw:~# echo -e "at\$qcrmcall=1,1\r\n" > /dev/ttyUSB2

打开另一个 Terminal 终端
root@nano-tw:~# cat /dev/ttyUSB2 

$QCRMCALL: 1, V4
OK

5、DHCP 获取IP 并进行上网确认？

root@nano-tw:~# udhcpc -i eth0
udhcpc: started, v1.27.2
udhcpc: sending discover
udhcpc: sending select for 10.4.201.79
udhcpc: lease of 10.4.201.79 obtained, lease time 7200
root@nano-tw:~# ping host.nvidia.com
