Ok, thank you! Where to put in the last row? At first in the script?
Next problem: isn't only USB0, I've got a dongle USB0, one USB3 and one ACM0. Want to use them free of thinking about that.

Thank you for your help! At first:
also you can hold the script till the tty device is availlable.
while [ ! -e "/dev/ttyUSB0" ]; do sleep 5; donethis snippet will wait till the file exists
or you could write something to wait for the network devices.
I don't think that this will work: I think the problem is that the argument, written from within /etc/rc.local, comes too late to initialize the Stick:
echo "12d1 1003" > /sys/bus/usb-serial/drivers/option1/new_idAnd without that there are no USB-devices.
And now the second: The script does not work for me. I guess it's because I have an extra (virtual) eth1 device for accessing my VDSL-Modem. When running the script it trys got get the gateway from this (wrong) device. There's no gw, so it starts immediately wan2 over 3g. Here are some informations:

it works! but you need add before this line "exit 0"
it works! but you need add before this line "exit 0"
I didn't contested that it works. But it does NOT work for me if the stick is connected while rebooting. Then the USBx-devices were not generated.
It works only if I put the stick in when the router is ready.
Some news:
I've changed the following:
From
WAN1_IF=`uci show network.$WAN1.ifname | awk -F = '{print $2}'`to
WAN1_IF=pppoe-wanand from
DEFAULT_GATEWAY=`uci show network.wan.gateway 2>/dev/null | awk -F = '{print $2}'`to
DEFAULT_GATEWAY=`route -n | grep $WAN1_IF | grep -v 255.* | awk '{print $2}'`assuming that it would work after these changes. But it didn't. It maked strange things and changed rapidly from wan1 to wan2.
The problem: my provider blocks pings onto the gateway (IP manually anonymized):(
~$ ping 2.0.9.1
PING 2.0.9.1 (2.0.9.1) 56(84) bytes of data.
From 2.0.9.1 icmp_seq=1 Packet filteredSo, in fact this script seems to not work for me 
Very nice work. Thanks for sharing.
I'm in a similiar situation that from time to time my provider's 4G wifi-modem loses its connection.
For that case I connected an old K-3565Z 3G USB stick (different provider, slower but more stable network) to my OpenWrt (bridged) router.
If I need to switch the network (WWAN<->WAN3G), I have to press manually the button on my WR1043ND.
So here for anybody who may be interested in my script:
# cat /etc/hotplug.d/button/buttons
#!/bin/sh
if [ "$BUTTON" = "wps" -a "$ACTION" = "pressed" ]
then
if [ -e /dev/ttyUSB3 ]
then
. /lib/functions/network.sh
if network_is_up wan3g
then
logger "3G network shutdown requested..."
ifdown wan3g
# wwan has to be restarted, otherwise the route wouldn't change.
ifdown wwan
ifup wwan
else
logger "3G network startup requested..."
ifup wan3g
fi
elif [ -e /dev/sda1 ]
then
if mount | grep -q "^/dev/sda1 "
then
logger "USB drive unmount requested..."
/etc/init.d/samba stop
umount /dev/sda1
echo 0 > /sys/class/leds/tp-link\:green\:qss/brightness
else
logger "USB drive mount requested..."
mount /dev/sda1
/etc/init.d/samba start
echo 1 > /sys/class/leds/tp-link\:green\:qss/brightness
fi
else
logger "WPS button pressed..."
fi
fiThis is kind of dirty (e.g. completely ignoring UCI, no error checking) and suited to my special configuration (if I plug a USB storage, the button has a different meaning).
So any improvements would be very welcome.
Additionally one has to modify /etc/hotplug2.rules as described here:
...
SUBSYSTEM ~~ (^net$|^input$|button$|^usb$|^ieee1394$|^block$|^atm$|^zaptel$|^tty$) {
...The LED settings for the 3G mode are done via LuCI.
I tried the script in OP #1. Unfortunately, it doesnt work for me. I have a Netgear WNDr3700 router connected to an ADSL modem (wan) and a 3g UMTS stick (wan2).
When the ADSL/'wan' is up, the route looks like this
