I am running Ubuntu 14.0.4 using and external modem. It will not recognize the modem. Is anyone familiar with modem and the problem?

Test this:

First, plug in the fax modem to an available USB 2.0 port.
Open a terminal: press Ctrl+Alt+T.
Run it:
```
sudo -i
apt-get install efax-gtk
modprobe usbserial vendor=0x0572 product=0x1329
dmesg | tail  -n 100
```
You are looking for something similar to this:

usb 2-1: Product: USB Modem
usb 2-1: SerialNumber: 35680336
cdc_acm 2-1:1.0: ttyACM0: USB ACM device
usbcore: registered new interface driver cdc_acm

You are interested in the serial address that Ubuntu has assigned to the USB fax modem. I’ve highlighted that information above in bold type.
The only thing you now have left to do is to plug in one end of a modular phone cord to the other end of the USB fax modem, and the other end of the modular phone cord into an available modular phone jack.
In efax-gtk select File Settings from the menus. On the second tab, you will need to enter the serial address that Ubuntu assigned to your fax modem when you set it up.

If your fax didn’t send successfully, review the fax log file to help diagnose any problems you might be having. You will know if there are any errors when sending the fax, since they will show up as red text in the text area that’s in the lower half of the efax-gtk window. Since all errors – minor and major – show up in red text, you will need to check to see which ones are important enough to follow up on.
