Micromax 3g datacard MMX377G Installation in ubuntu, lubuntu, kubuntu, xubuntu ...

Installing usb modem in linux is quite difficult to new user like me in linux, I also got trouble to install usb modem driver in LUBUNTU. so searched over internet and get a good sollution...

here is the process

1. Pre-check before install the software

Insert the SIM card into the 3g dongle and plug the device into your computer or laptop USB Port.

Now check the plugged device using following command. Open your terminal (ctrl+T) and enter this command.

?

>ls /dev/sr*

Above command must be return the all devices the SCSI-CDROM’s that mounted on your machine. You may get the below result in your terminal

/dev/sr0

If you have more than one device connected you may see like below. To confirm which one is correct device that linked with your dongle. We need to unplug and execute the same command and see which device is disappeared from previous list. Then re plug and execute the command, now you can see that device back. Your current device maybe linked with /dev/sr1 or /dev/sr2 or anything else.

/dev/sr0 /dev/sr1 /dev/sr3

There is another case also, when you run ls /dev/sr* comand you may receive the following result. If you get this message, the software is already installed. We will see unintallation step at last. If you are not getting this message no problem go with step 2.

ls: cannot access /dev/sr*: No such file or directory

2. Mount the device.

Navigate to users Home directory in your terminal and enter the following command to mound the device.

?

>sudo mount /dev/sr0 /mnt

It will prompt the password, after entering the password you should receive following message

mount: block device /dev/sr0 is write protected, mounting read-only.

Now you can check the result of mount by executing below command

?

>cd /mnt  >ls

Now you will see all the installation packages of the device. We can notice see the two different package for 32-bit and 64-bit machine. We need to install the package according to that.

32-bit = 3g_modem_connect_D301_MMX_i3386.deb
64-bit = 3g_modem_connect_D301_MMX_amd64.deb

3. Installation, Lets consider for 64-bit, enter the following command.

?

> sudo dpkg -i 3g_modem_connect_D301_MMX_amd64.deb

When Installation finished. Unplug your Micromax 3g Datacard from your computer and re plug. Now it will connect to internet automatically, if device lock and Pincode is disabled.

4. We can check the COM port using this command.

?

>ls /dev/tty*

Now you can notice at the end of list with following

/dev/ttyUSB0
/dev/ttyUSB1
/dev/ttyUSB2
/dev/ttyUSB3

4. Connect to the Internet.

?

>sudo 3g_connect.sh ttyUSB0

When you enter this command, you will be getting connection progress, finally you will receive “pppd is connected” message.

Note : If your device lock is enabled, it will ask device code. so we need to enter the device code for further process. Default device code is “1234″.Share on TumblrNote : If your device lock is enabled, it will ask device code. so we need to enter the device code for further process. Default device code is “1234″.

and if you cant find any device in /dev/sr* (sr0,sr1...)

then follow this step...

Please remove the modem, wait for about 10 seconds. Then plug it back in --> wait for about 1 minute --> run the following commands and post back their outputs -

Code:

lsusb dmesg | tail -20 lsmod usb-devices | grep -iA14 -B4 2020 modprobe -c | grep -i 2020.*4010

..And, just to see if we can get the drivers located on the modem itself, please try this -

Code:

sudo sed -i '/^Disable/ s:0:1:' /etc/usb_modeswitch.conf

Now unplug --> replug the modem and re-check-

Code:

lsusb

Do you see the ID 2020:0002 device again (or anything other than 4010 with 2020)? If not, reboot and try again. Now? If yes, what does this tell us -

Code:

ls /dev/sr*

PS:

The above change to the /etc/usb_modeswitch.conf file will disable the modeswitching so that we can access the storage (virtual cd) part of the modem. To be able to use it as a modem again, you will have to change the value "1" back to "0" with -

Code:

sudo sed -i '/^Disable/ s:1:0:' /etc/usb_modeswitch.conf

However, I suggest you keep it to "1" until we can copy the driver off its storage part. As soon as it is done, change it back to "0" with above command (you can of course also edit it with your GUI text editor, opening it as root).
