= Connect using USB Ethernet Gadget/RNDIS driver =
== Overview ==
The Linux kernel has a class of drivers called USB Gadgets that allow you to use USB as a transport for a number of different protocols like serial, virtual file systems and Ethernet devices. The USB OTG connector supports using the Ethernet Gadget to create a networking device over USB. From the client's (and host's) perspective this driver simply appears as another Ethernet device, enabling us to have Ethernet access on the board by hooking them up to a desktop, so this USB slave device can communicate with a properly configured USB host.
== Requirements ==
There are some requisites to follow this guide:
*IGEP Processor Board
*Host PC

=== Linux ===
'''NOTE:''' You should have the usbnet module available for your Linux kernel. On most distributions, this is the case by default. If this is not the case for your distribution, you will need to enable USB networking support in the kernel. If you build your own kernel then you want 'CDC Ethernet support' in USB Network adaptors. IGEP SDK Virtual Machine has this module enabled.
*In the file /etc/network/interfaces, you should add:
...</pre>
*Connect to IGEP device

The authenticity of host '192.168.7.1 (192.168.7.1)' can't be established.
