I have a  huweai e1732 modem which i want to use as simple smsgateway for my personal use and outgoing voice trunk for asterisk .

As soon as I connect it to usb ,linux detects it as external storage and never shows as ttyUSB in /dev list .

To make it work as serial modem i had to install usb_modeswitch

[root@sriba usb_modeswitch.d]# yum install usb_modeswitch
