Hello

I know there is a way but it is difficult to find...HELP!!

I would like to have my Linux (sam9263) utilizing the slave USB port to provide ethernet like service when connecting to a usb host.

To make it clear: a PC connects with a usb cable to the slave port of the sam9263 and sees an ethernet device. I guees, the standard PC provides already this kind of capability. Now, my sam9263 running linux needs to be the slave counter part.

linux sam9263 (SLAVE USB) ------ (HOST USB) any PC (sees ethernet device on usb)

We have the microhttpd running already on the sam9263. Up to now the PC connects through standard LAN port connection. Now we would like the usb slave port to be the port.

What needs to be done? We are using biuldroot 2011.02 and Linux 2.6.30.

I came along something like "gadget". Is this helping? and how??

Thanks indeed for any contribution.

no idea in this world wide web...

Am I the only one wo wants to use the USB Device Port under Linux?

Best wishes
Thomas

Yes, you'd want to use the USB gadget drivers. From my notes:

Ethernet bridge over USB

• first, load the ethernet gadget driver if needed (or build it into your kernel):
# insmod /lib/modules/2.6.30-ts-armv5l/kernel/drivers/usb/gadget/g_ether.ko
• assign the new usb0 driver an ip:
# ifconfig usb0 192.168.1.1
• plug in the device port to a PC, it should detect the connection
• if the PC asks for drivers, point it to the linux.inf file (located in LINUX source /Documentation/usb) using the have disk method (see http://docwiki.gumstix.org/Windows_XP_usbnet). This is for XP, not sure on others.
• setup the new USB network on the PC with a fixed IP in the same subnet, ie: 192.168.1.10 (must be a different subnet than the Ethernet ports)
