Client error on startbond.sh: Error: any valid address is expected rather than "dev".

run "ip route show" and see what position in the string the gateway address is for usb0. Probably need to change line 71 to :

tunnelInterfaceGW=$(ip r | grep 'default.*'${tunnelInterface} | awk '{print $9}') specifically for usb0.

You can also add a check like this:

tunnelInterfaceGW=""
# let's read out the default gateway from the main table
if [ "$tunnelInterface" = "qmimux0" ] || [ "$tunnelInterface" = "qmimux1" ] || [ "$tunnelInterface" = "ubs0" ] ;
then
    tunnelInterfaceGW=$(ip r | grep 'default.*'${tunnelInterface} | awk '{print $9}')
else
    tunnelInterfaceGW=$(ip r | grep 'default.*'${tunnelInterface} | awk '{print $3}')
fi

(For simcard interfaces such as qmimux0 / qmimux1 the gateway address is also at position 9 in the output string)

Unplug the internet connections from the connector and reconnect them. It worked for me.
