I want to configure EVDO Usb Modem in Ubuntu 10.10 I insert my usb modem to laptop and check the usb is detected or not using $sudo lsusb and the result is:

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 201e:2009
Bus 002 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 001 Device 003: ID 14cd:6600 Super Top USB 2.0 IDE DEVICE 

Bus 002 Device 002: ID 201e:2009 is my us device. and than I execute command $dmesg | grep -e tty

[    0.000000] console [tty0] enabled

Why converter disconnected from ttyUSB2 ?

and than I try to execute command $sudo wvdialconf

sorry, no modem was detected!  Is it in use by another program ?
did you configure it properly with setserials ? 

I change the same type usb modem from my friend, but I still get error above.

UbuDSL is for DSL modems. EVDO (en.wikipedia.org/wiki/EVDO) is mobile broadband. Instead, if you are under GNOME/XFCE you could try the NetworkManager through its applet. There's a "Mobile Broadband" feature which happens to be working 100% of the times with my GSM/UMTS/HSDPA modems. –  Uqbar Apr 14 '11 at 13:24
    
I've found the solution. First, I must connecting the USB modem from windows operating system, and disconnect the modem. After that restart the computer, and choose Ubuntu Operating system. –  adisembiring Apr 14 '11 at 15:38

You could give UbuDSL a try, though it hasn't been updated in a little while, and I'm not 100% sure if your modem will be supported, but it might just work.

BTW I found a pair of links that might help (though documentation otherwise seems a bit lacking):
