    Question Network Manager Can't Detect My ZTE USB 3G Modem!

    Hello, I am using ubuntu 12.10.
    I use a ZTE USB 3G Modem to connect to internet. I connect that modem through a driver software which was provided with the modem. This modem works fine. I can browse , use apt-get through terminal.
    But the problem is network-manager cant detect my modem. It shows nothing in the top bar. Because of this I -

    1. Can't use Ubuntu Software Center
    2. Can't use VPN services
    3. Can't create wifi hotspot

    First of all i am telling what i have noticed about this modem:

    1. When I connect this modem first time that driver software can't detect it. This time ' lsusb ' command give this http://paste.ubuntu.com/5691060/ (I cant understand how to add link with text here!). After unplugging and plugging for 2-3 times that software can detect modem and output of lsusb changed to http://paste.ubuntu.com/5691067/ . But if i connect modem before starting Ubuntu that driver software can detect modem at first time!!
    2. I have tried to connect this modem through ' Mobile Broadband ' option but unfortunately this option can't detect my modem under ' create a connection for this mobile broadband device ' option.
    3. I think that driver software use wvdial to connect to the internet as I have to install wvdial before installing that software.
    4. Also used sakis3g. sakis3g can connect my modem but this also can't solve the network-manager problem.

    Now I am telling what I have done till now to solve that network-manager problem:

    I have tried this code with root privilege:
    Code:
    echo vendor productID > /sys/bus/usb-serial/drivers/option1/new_id
    It didn't work. Actually it shouldn't. Its clearly saying to edit new_id file with vendor and product id in /sys/bus/usb-serial/drivers/option1 directory. But i have no option1 folder in /sys/bus/usb-serial/drivers directory! I have only a folder named generic in that directory. And new_id is also present there.

    so i have tried this code with root privilege:
    Code:
    echo vendor productID > /sys/bus/usb-serial/drivers/generic/new_id
    it didn't work too. One more thing its confusing what will be my productID for this code 0154(which lsusb finds before modem gets detected by driver software)? or 2003(which lsusb finds after modem gets detected by driver software)?

    As option1 folder is not present in the /sys/bus/usb-serial/drivers directory I have tried to create this folder manually with root privilege:
    Code:
    mkdir /sys/bus/usb-serial/drivers/option1
    but it gives this error message "mkdir: cannot create directory `/sys/bus/usb-serial/drivers/option1': No such file or directory".

    Thats all. Now my question is whats wrong? Is there any solution to get my modem detected by network-manager?

    I had to disable usb3.0 in BIOS in order for the 3g dongle to be detected without trouble
