Gammu stops receiving SMS after a while

Question

I have a problem that's been bugging me for a while now. I've been searching for solutions for 2 weeks now without any result. These guys have the same problem as me but no answers there..

I'm running gammu (1.31) and gammu-smsd on a Rpi with raspbian. Using a Huawei E367.

Don't know why I got 3 devices /dev/ttyUSB0, /dev/ttyUSB1, /dev/ttyUSB2 Since I don't know the difference between these I tried different settings and got it running with the following; gammuconf ttyUSB0 and gammu-smsdrc ttyUSB2. Both as root and normal users.

Sending SMS works great. Then comes the problem. Receiving SMS works for a while, then just stops. If I reboot the system it starts to work again. For a while, but the same thing happens after a while.

I guess the early warnings are before my modeswitch command kicks in. in rc.local:

sudo usb_modeswitch -v 0x12d1 -p 0x1446 -V 0x12d1 -P 0x1506 -m 0x01 -M 55534243123456780000000000000011062000000100000000000000000000  -I

I have the same Problem, so I wrote a shell script to reactivate the clean-quick /dev/ttyUSB[0-2] device, and then added it to cron job

*/5 * * * * /home/sysadmin/scripts/reanimate-usb-stick.sh >/dev/null 2>&1

reanimate-usb-stick.sh

#!/bin/bash

export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"

USBDEVICES=$(ls -l /dev/* | awk '/\/dev\/ttyUSB[0-7]/ {print $6}' | wc -l)
DEVICEINFO=""
DEVICEPORT=""


if [ $USBDEVICES = 0 ]
        then
                datas=$(lsusb | grep -i hua | awk '/Bus/ {print $6}' | tr ":" "\n")
                counter=0
                for line in $datas
                do 
                        counter=$((counter+1))
                        if [ $counter = 1 ]
                                then
                                        DEVICEINFO=$(echo "$line")
                        fi

                        if [ $counter = 2 ]
                                then
                                        DEVICEPORT=$(echo "$line")
                        fi
                done
    usb_modeswitch -v $DEVICEINFO -p $DEVICEPORT -J
    echo "$DEVICEINFO - $DEVICEPORT"
    else
        echo "ALLES OK : $USBDEVICES"
        exit
fi
