How to configure TATA Photon+ EC1261 HUAWEI
I have installed Ubuntu 12.10 (64 bit) on Dell inspiron 7520 laptop having Intel i7 3rd generation processor. I am trying to connect mobile broadband device and am unable to establish a connection.
1. When I try to add mobile broadband connection from 'network connections->mobile broadband' I can not see modem (huawei) in a drop-down in 'New connection' window even if it is connected to laptop.
2. When I ran command lsusb, output was:
$ lsusb
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 003 Device 002: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800/E173 (HSPA modem)
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0bda:0129 Realtek Semiconductor Corp.
Bus 001 Device 004: ID 0c45:648d Microdia
Bus 002 Device 003: ID 8087:07da Intel Corp.
Here, we can see that 12d1:1446 Huawei Technologies Co is identified. So I think that ubuntu is not able to recognize it as a modem.
3. When I checked usb_moedswitch.rules file, I found entry for this device.
I ran command
$ cat /lib/udev/rules.d/40-usb_modeswitch.rules
and in that file I found entry:
#Huawei, newer modems
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1446", RUN+="usb_modeswitch '%b/%k'"
Ubuntu is not able to recognize this device as a modem, even if this entry is present in this file.
4. Just for a trial, I ran command:
$ usb_modeswitch -H -v 12d1 -p 1446
and got output as-:

Question I am not sure what is the exact problem and how to solve it. Is it some kind of driver's problem? I am not expert in Ubuntu. Could anyone help me out?
Thanks
