executed after the configuration sequence described above:
modprobe usb_f_ecm
modprobe libcomposite
modprobe configfs
cd /sys/kernel/config/usb_gadget
mkdir -p g1
cd g1
echo "0x1d6b" > idVendor
echo "0x0104" > idProduct
mkdir -p strings/0x409
echo "0123456789" > strings/0x409/serialnumber
echo "Renesas." > strings/0x409/manufacturer
echo "Ethernet Gadget" > strings/0x409/product
mkdir -p functions/ecm.usb0
mkdir -p configs/c.1
mkdir -p configs/c.1/strings/0x409
echo "ECM" > configs/c.1/strings/0x409/configuration
if [ ! -L configs/c.1/ecm.usb0 ]; then
ln -s functions/ecm.usb0 configs/c.1
fi
echo 11e20000.usb > UDC
echo 11e20000.usb > /sys/bus/platform/drivers/renesas_usbhs/unbind
