I have purchased new vodafone usb modem (ZTE K3770-z) and tried to connect it with ubuntu 11.04. But it is not automatically detected on ubuntu.

I have installed windows 7 and ubuntu 11.04 on my laptop.

To detect the modem on ubuntu I did the following steps :-

1) Connect the modem with laptop and boot the machine with windows 7 2) After detecting the modem on wndows, restarted the machine and enter into ubuntu.

Does anyone know any solution to detect the modem automatically on ubuntu?

Thanks in advance.

eject your device from terminal or disks.

1)you can find disks at search of to the cd rom of your modem and at left top you could find a triangle above a line at the center of three options. it will say "eject the medium in the drive". click at here.

2)In terminal, type eject & press enter

you could find your modem at nm after 12 sec,

click here to add your device id to usb switch mode for auto eject at startup

for refreshing the network manager from terminal try the command,

sudo service network-manager restart

press enter and type your password that is, you can stop restarting of your computer or replugin of your modem

May be late for you, but try this in your Windows 7 OS:

Go to Device ManagerUniversal Serial Bus ControllerGeneric USB Hub (right-click) → Properties → under Power Management tab, un-check "Allow the computer to turn off dis device to save power".

This may work.
