the script will be placed in /etc/hotplug.d/usb/30-rtl8152.sh

#!/bin/sh

[[ "$ACTION" = add -a "$DEVTYPE" = usb_device ]] || exit 0
logger -t "RTL8152 Script" "Checking USB";
if $(lsusb | grep "0bda:8152");then
        logger -t "RTL8152 Script" "USB Connected";
        until $(uci get network.wan2.ifname);do
                if [[ $(uci get network.wan2.ifname) = wan2 ]];then
                        logger -t "RTL8152 Script" "Applying to WAN2";
                        uci set network.wan2.ifname='eth1';
                        uci set network.wan2.hostname=$(uci show system.@system[0].hostname | sed 's/^.*hostname=//g' | sed "s/'//g");
                        uci commit network.wan2;
                        sync;
                        ifup wan2;
                        service network reload;
                fi;
        done;
fi;
logger -t "RTL8152 Script" "Script Finished";

exit 0

why logread -e "RTL8152 Script" only print last if ("RTL8152 Script" "Applying to WAN2") ?
