= Connect using USB Ethernet Gadget/RNDIS driver = Overview ==
The Linux kernel has a class of drivers called USB Gadgets (http://www.linux-usb.org/gadget/) 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.

1. During the first seconds the module is recognized as OMAP3430. Avoid the installation of this device and wait until ''RNDIS/Ethernet gadget'' is detected by the operating system.
