I was finally able to connect to the internet via USB(still dont know what the problem was, I just reinstalled my Host Ubuntu)
I followed the instructions given by Robert and ran the script on my Host PC https://github.com/RobertCNelson/boot-scripts/blob/master/network/doc-debian-setup.md . And this on the BBB " sudo /opt/scripts/network/usb_linux_usb0_ics.sh " *But ,the above instructions apparently doesn't save the configuration* , and the default gateway disappears after the BBB is rebooted. So I have to execute this command sudo /opt/scripts/network/usb_linux_usb0_ics.sh every reboot. Do I still need to save the config in /etc/network/interfaces something like : iface usb0 inet static address 192.168.7.2 netmask 255.255.0.0 network 192.168.7.0 gateway 192.168.7.1 OR does it have to be through a bash script which runs has to be set to autorun mode after boot ?
