Re: [LUG] MTN CDMA usb modem under linux

Peter and the list,

I am able to get the USB/Serial cable to load properly and the /dev/ttyUSB0 node is created.

That's is not the problem, the problem is trying to use /dev/ttyUSB0 as the modem port.

I have pointed wvdial, pppconfig and even minicom (yes, I did minicom -s as root) to /dev/ttyUSB0 but there doesn't seem to be any response from the modem.

Was hoping that someone on the list has actually been able to use this modem and could provide their config.

Cheers,
Joseph

The issue with the MTN modems is NOT the modem.

It's the Texas Instruments USB-serial cable.

You need to get it working with udev. Here are instructions I posted to someone:
-------------------------------------------------------------------------------------------

 If you're using a HUAWEI modem - such as MTN's YelloLine, you need to get the USB-serial dongle working with Linux.

Newer versions of Linux use Hal & UDEV to handle devices and getting the modem in a state where your distro "sees" the modem is a simple 2-step process.

1. Edit /etc/udev/rules.d/50-rules and add the following line:

SUBSYSTEM=="usb", ACTION="" ENV{PRODUCT}=="451/3410/*", RUN+="/etc/udev /scripts/ti_usb_3410_5052.hotplug %p"

2. Copy the attached script to /etc/ udev/scripts/ti_usb_3410_5052.hotplug

Voila. When you plug in, your modem is seen as /dev/ttyUSBX (usually ttyUSB0)

Configure using your favourite tool - kppp, wvdial, etc.

3. (optional)
If you like your /dev/modem to be a permanent soft-link, then edit /etc/udev/static_devices.txt and add
modem l ttyUSB0

That's an L, not a ONE.

I have some instructions that were forwarded to Rob Gipman from Reigner Battenberg from a previous thread on this subject.  See below.
 
Hope this helps.

"If you are using a new kernel >=2.6.11, the driver for the usb-serial (from Texas Instruments) cable is in the kernel.
 
These are the instructions I gave someone for how I got it working on SuSE 9.1.  Should be easy to 'translate' for your distribution:
 
-------------------------------------------------------------------------------------------------------------------------
 
1.    Update the hwinfo, udev and mkinitrd packages.  You can find them here:  http://ftp.gwdg.de/pub/linux/suse/people/agruen/i386/  
 
2    Download the 9.3 kernel from
 
3    Create an executable script file called  /etc/hotplug/usb/ti_usb_3410_5420 (or  /etc/hotplug.d/usb/ti_usb_3410_5052.hotplug depending on yr dist.) and paste the contents of the attached script.
 
4    FINALLY.  Create a soft link
        ln -s /dev/ttyUSB0  /dev/modem
 
You're done!  Run YaST and configure your modem.

Subject: [LUG] MTN CDMA usb modem under linux

Am trying to get the MTN modem working under linux but having lots of trouble

After extensive searching on the internet (including the previous threads on this list), I have been able to get the cable loaded at ttyUSB0, by upgrading the kernel and adding 'options usbserial vendor=0x451 product=0x3410' to /etc/modules.conf (ubuntu: /etc/modprobe.d/options).

Problem is, when I set wvdial, pppconfig and even minicom to use ttyUSB0 as modem port, there seems to be no communication, nothing on the phone screen while dialing.

I have tried this phone under windows, it works well (using MTN supplied drivers)

Has anyone set this up under linux? Please post your experience.

Cheers, Joseph
