First of all my goal is this, have a computer as a peripheral device to connect it to anyone's computer with ssh protocol or web. The idea is doing this by using a plug and play USB cable .

Facts that I know:

  • USB is designed as Master/Slave Architecture, so simple connection doesn't work beacuse both computer are acting as a host.
  • Ethernet is the simplest solutions, I know but I don't want to loose that interface.
  • There is a cable that makes a connection as USB PC to PC cable link. But I am not sure if we can get ssh work with this.

Searching I found the RNDIS protocol, I think this maybe has a solution to my problem but I don't what is this for exactly. Here it says:

RNDIS support allows a PC to talk to a Linux-based embedded system over USB by making the embedded system look like a USB attached Ethernet adapter.

This is pretty much what I need. Could somebody guide me on what I want? Maybe I am missing the point, I do not know.

I have compile a new kernel with the USB GADGET DRIVERS options and setup g_ether.ko module. When I tried to load the module

sudo modprobe g_ether
FATAL: Error inserting g_ether (/lib/modules/3.13.2/kernel/drivers/usb/gadget/g_ether.ko): No such device`

and

ls /lib/modules/3.13.2/kernel/drivers/usb/gadget/

I have often seen that embedded systems have a USB slave port (for communication and/or providing power to the board). you wont have that on a normal computer. –  Anthon Feb 17 at 19:45
