Hi buddies....So nice to tell you that Ubuntu 10.10 has been released. Collect yours now.......!! volunteers are requested to order CDs for distribution.......Lets spread the word of UBUNTU!!

New GP modem Huawei e1550 in Ubuntu Lucid Lynx

I was having a lot of problem using the new modem sold by GP itself to work with ubuntu. The Huawei e1550. The modem also has a card reader!. but i liked the previous one as it seemed to me to work faster. . .

by the way i came up to a solution here. It worked nicely to set up the modem to be detected automatically by lucid..(i was not even able to detect my device previously)

I re describe the steps here-

run in terminal

$sudo lsusb

you should see a list of usb stuff 
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 004: ID 12d1:140c Huawei Technologies Co., Ltd.

now we can see our ID of modem - 12d1:140c

Create a new rule for udev:
$sudo gedit /etc/udev/rules.d/15-huawei-155x.rules

Type the following on the file just opened:

RUN+="/lib/udev/modem-modeswitch --vendor 0x$attr{idVendor} --product 0x$attr{idProduct} --type option-zerocd"

Then, save and exit. The next time you plug in your USB modem, your system should automatically switch it to USB Modem mode and you’re good to go.

The new mobile broadband connection wizard should appear after you re plug-in the modem. follow the steps to connect.

if the connection is slow try restarting the mode

$sudo apt-get install usb-modeswitch
$sudo usb_modeswitch -v 0x12d1 -p 140c -R -W

Does it work on any version of Linux?

I havent tried in all linux versions. but it worked on ubuntu.

by the way not all linux distributions require this tweak. Some of them identifies the modem automatically.

Thanks for the nice post. I have tried your instruction & getting work with lucid but after editing "etc/udev/rules.d/15-huawei-155x.rules" file i cannot use any pen drive. when i delete 15-huawei-155x.rules file I can use pen drive. But modem again gone...

Can you help me?

@touhid: sorry for the late reply. That is really a weird problem. I havent faced it. Maybe you should try googling something about udev rules conflict.
