BQ Aquaris E5 не распознан как GSM модем

мой BQ Aquaris E5 (ubuntu edition) не был обнаружен как GSM модем в Ubuntu 15.10 desktop edition. Поэтому я попробовал следующий скрипт:

vendor=
product=

cat <<EOF > /etc/usb_modeswitch.d/mobile
DefaultVendor= ${vendor}
DefaultProduct= ${product}
TargetVendor= ${vendor}
TargetProduct= ${product}

service modemmanager restart
service udev restart

modprobe option
sleep 2
vndr=`printf "%x" ${vendor}`
prdt=`printf "%x" ${product}`
echo "$vndr $prdt" > /sys/bus/usb-serial/drivers/option1/new_id

выполнил приведенный выше сценарий оболочки следующим образом:

detect_usb 0x2a47 0x0c02.

после этого в /var/log/syslog появилось следующее сообщение:

запуск lsusb на моей системе показывает следующее:

Bus 003 Device 004: ID 2188:0ae1  

но попытка отправки AT-команд модему (обнаружено как /dev / ttyUSB0), неудачи. Ниже приведен пример скрипта на языке Python-gsmmodem используется:

!/usr/bin/env python
