3G modem detection


I am unable to detect my Micromax 3G USB modem I bought for MTNL connection in Ubuntu 9.04, though it automatically loads software already on the modem and works fine in Windows XP. Any guide on how to connect Internet using this modem?

Please post 'lsusb' ouput and 'dmesg | tail'

anyway, do you install wvdial? try 'wvdialconf' first

(you might need to use sudo for command)

Linux support for BSNL 3g modem MMX300G

Today I have successfully connected my BSNL 3g Modem (micromax -mmx300G) in Ubuntu linux. Actually the modem when connected will be detected as Virtual CD ROM. To use the modem u need to switch the device to usb-serial mode. The product ID will be different after switching mode. Just use the ID with modprobe command. Then u are done. Sure you will get the connection and u will be able do all that u can do with internet.
If want any switching between GSM network and HSPA network, do the following:
At extra initialisation comands just add the entry
AT+COPS = 0,0,"cellone",0 ---- for GSM mode
or
AT+COPS = 0,0,"cellone",2 ---- for UMTS mode.

Shortly I'm going to post complete set of details.

Yes, I tried to use wvdialconf, but it says no modem. Whenever I connect the 3G modem, it shows up as a CD type icon as Modem. I got following after unmounting it:

lsusb gives this output

Bus 001 Device 004: ID 1c9e:f000
Bus 001 Device 003: ID 0ac8:c326 Z-Star Microelectronics Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 0a5c:2101 Broadcom Corp. A-Link BlueUsbA2 Bluetooth
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

And, dmesg gives the following

[ 247.247814] sr0: scsi-1 drive

[ 247.248666] sr 2:0:0:0: Attached scsi CD-ROM sr0

You can use USB_modeswitch to change it back to modem. Your modem now functions as ZeroCD.

Adding some info from usb_modeswitch.conf as to your lsusb output
Code:
