Create new ethernet usb network interface on Linux
this is ethernet-over-usb
https://en.wikipedia.org/wiki/Ethernet_over_USB
without external hardware you can try the CDCether
kernel module and ethtool
( then you can only connect to a usb device that operates in usb device mode )
( https://developer.ridgerun.com/wiki/index.php/How_to_use_USB_device_networking , http://tldp.org/HOWTO/Motorola-Surfboard-Modem/usb.html, http://www.linux-usb.org/usbnet/ )
else you need a physical adapter for this. the adapter translates between the protocols and the different hardware interfaces.
in usb protocol can only be one host in a network, therefore you need at least a host-to-host cable ( http://www.linux-usb.org/usbnet/ ) if you want to connect two usb host devices, i.e. two pcs
required kernel module ( driver ) when using a physical adapter is either usbnet
( with its minidrivers ) or usb-eth

I'm trying to create a usb based ethernet device on my computer, basically I want to tell my computer (linux based) that one of its usb ports is actually an ethernet port. I have done extensive research and while it's supposed to be possible, I can't find any examples of code / commands to run.
According to wikipedia:
The USB-eth module in Linux makes the computer running it a variation of an Ethernet device that uses USB as the physical medium. It creates a Linux network interface, which can be assigned an IP address and otherwise treated the same as a true Ethernet interface. Any applications that work over real Ethernet interfaces will work over a USB-eth interface without modification, because they can't tell that they aren't using real Ethernet hardware.
So in theory, this should be possible, I just need some help or a gentle nudge in the right direction to get this thing rolling. What I'm NOT trying to do is plug a usb to ethernet dongle/adapter into my computer, I have several of those lying around and that doesn't help me out at all.
