Hi Grant
we have already tested what you are suggesting, but nothing happens.
I'm supposing the problem comes from interrupts.
In fact USB is still alive, every 5 sec. we can see some timeout messages.

Ideas :( ??
Thanks J
P.S. Using lite5200 EVB USB works well using almost same drivers.

No. Configuring the Ethernet pins for USB IO is just a pin routing
board setup task. You do need to make sure U-Boot sets up the
port_config register correctly, but it doesn't impact the device tree.
You don't need to change any of the values in the USB node.
However, if the Ethernet device is unused then you should remove the
Ethernet node from your device tree.
