usb_modeswitch to help you.
After switching to the serial ports mode (if you want it to work in this mode), they will be displayed as /dev/ttyUSB*

so what’s wrong?

root@raspberrypi:/tmp# /dev/ttyUSB*
bash: /dev/ttyUSB*: no file and catalog

$ls -l /dev/gsm* > catalog not found,

use usb_modeswitch not just install it, try google your modem:

i try

usb_modeswitch -v 12d1 -p 14fe -V 12d1 -P 1506 -M “55534243123456780000000000000011062000000100000000000000000000”

after restart back to 12d1 14fe all the tiem

Put in /etc/rc.local

Is it supposed to be this way?

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

exit 0

usb_modeswitch -v 12d1 -p 14fe -V 12d1 -P 1506 -M "55534243123456780000000000000011062000000100000000000000000000"

you should add before exit 0

The reason behind the modem not located is a bandwith problem . Because many times we don’t even know how to set the bandwidth properly and it’s a huge problem for us then. I believe that if you are properly set up the bandwidth ten you don’t even face Netgear Router Password Issues and it’s really the main solution for you.
