Franklin Wireless's CDU 550 EVDO USB modem isn't detected by Ubuntu 7.10 out of the box (Fedora 8 does detect it). If you are like me and using this modem with Ubuntu or another distro which doesn't detect the modem, a solution:

We need to create a shell script. Open gedit (or the text editor of your choice). Copy and paste the following text:

#!/bin/bash
# usb : acm
echo -e "\033[32mMake Modem Device\033[0m"
for i in `seq 0 2` ; do
mknod /dev/ttyACM$i c 166 $i
done

echo -e "\033[32mMake Dual Mode Device\033[0m"
for i in `seq 0 2` ; do
mknod /dev/ttyUSB$i c 188 $i
done

echo -e "\033[32mMake driver rule\033[0m"

Next save the file as a shell script - with a name you will remember, for example: modem.sh

Make the file executable. From the terminal cd into the directory containing the file

sudo chmod a+x modem.sh

then execute the file:

sudo ./modem.sh

Your modem is now configurable - use wvdial - or networking from the system menu to set up your access. The modem is on /dev/ttyACM0
