Hi Laurent,
I succeeded using the Ethernet gadget. If it can be of any help, here is
what I did:

DEVICE SIDE:
1. Install the UDC driver at91_udc.ko
# insmod at91_udc.ko
2. Install the Ethernet gadget driver
# insmod g_ether.ko


HOST SIDE (i386 linux 2.6.8 Mandrake 10.1)
1. Load the usbnet driver with:
$ modprobe usbnet

Now connect the device and the host with the USB cable. A new usb0 network
interface will be created on each side.
Give them IPs and route them to the other side USB IP.

DEVICE SIDE

# ifconfig usb0 192.168.52.45
# route add 192.168.52.200 dev usb0

HOST SIDE
$ ifconfig usb0 192.168.52.200
$ route add 192.168.52.45 dev usb0

Now you can do pings or any other network activity via USB.

Regards,
Héctor
