Few months ago, I configured citycell zoom in my friend’s pc. That was Huawei modem and was much easy to configure. First tried to detect modem using wvdialconf in the terminal. Then just edited wvdial.conf file (/etc/wvdial.conf) with the detected path and after dialing wvdial cdma in the terminal it was successfully connected.
But recently in the eid vacation when i was in chittagong, i’ve bought citycell zoom with ZTE usb modem for using internet there. It was very much easy to setup and connect to internet in windows XP but failed to do so in ubuntu. First i tried to detect modem using wvdialconf. But It was showing a msg like failed to detect modem. then tried to grep tty using dmesg | grep tty but failed again, then tried to view modem using cat /proc/bus/usb/devices. But i haven’t found anything like devices in cat /proc/bus/usb/devices directory.
Anyway, Here is what you have to do to detect ZTE usb modem.
In ubuntu, you have to uncomment few lines to explore devices directory. So edit mountdevsubfs.sh file. ( ** No need to do this in fedora core, it will automatically detect devices in /proc/bus/usb/ directory)
sudo gedit /etc/init.d/mountdevsubfs.sh
and uncomment following lines from this file.
# Magic to make /proc/bus/usb work
mkdir -p /dev/bus/usb/.usbfs
domount usbfs “” /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount –rbind /dev/bus/usb /proc/bus/usb
Now start the service
/etc/init.d/mountdevsubfs.sh start and reboot your pc.
Then check if the USB device is detected properly
cat /proc/bus/usb/devices
Try to find some output like this
T: Bus=07 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=16 #Cfgs= 1
P: Vendor=19d2 ProdID=fffd Rev= 0.00

S: Product=ZTE CDMA Tech

I:* If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=usbserial_generic
E: Ad=81(I) Atr=03(Int.) MxPS= 16 Ivl=128ms
E: Ad=8a(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=0b(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
I:* If#= 1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=usbserial_generic

E: Ad=06(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms

E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=05(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
Now probe for this USB device
modprobe usbserial vendor=0×19d2 product=0×fffd
You are done!!
Now run wvdialconf in the terminal Or you can edit /etc/wvdial.conf file and paste these following lines.
[Modem0]
Modem = /dev/ttyUSB0
Baud = 230400
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
[Dialer cdma]
Username = waps
Password = waps
Phone = #777
Stupid Mode = 1
Inherits = Modem0
Now you can connect to internet by applying the following command in terminal.
wvdial cdma
Using the same procedure, i’ve configured this modem in my office (fedora) also.
Thats it! Enjoy. 
Note: For Ubuntu intrepid 8.10 and Ubuntu 9.04 jaunty jackalope, Please see my comments, i hope that will help you to connect to Internet

I reinstalled ma operating system (XP)and observed everything goes fine if I’m not connected! why is this happening??plz help me out…

If your pc is infected then only formatting one drive and installing OS is not enough :). To confirm avoiding virus/spyware infection you need to format all the drives, then install OS.
Seems to me, u r having spyware problem :-s Do you have updated anti-virus installed in your pc?
Anyway, no need to do this now
You need to download few things (use any other pc for this) if you are using mcafee then Download and setup latest super dat of Mcafee (sdat 5415 may be the recent one) and download any reliable anti-spyware software and check your pc or setup HijackThis to your pc and see the log and then remove unwanted applications from there.

I am facing same problem. Recently I installed ubuntu. I want to setup zoom internet in this OS. I am using Alcatel Music set. For your information, I am very much new in linux. Please help me.
#5 by shabuz - November 2nd, 2008 at 04:33
@ Harun
Connect ur device with usb port. Then try to detect modem. Open a terminal and type
sudo wvdialconf
It will automatically detect your modem. See the file located in /etc/ directory. to do this, type
sudo gedit /etc/wvdial.conf
You will see whether your modem is detected successfully or not. If detected then just type
sudo wvdial cdma
You will be connected
But if wvdialconf can’t detect your modem properly. then please read my post and follow the instructions.

Scanning your serial ports for a modem.

giving up.

Sorry, no modem was detected!
Is it in use by another program?
Did you configure it properly with setserial?
#12 by shabuz - November 12th, 2008 at 04:18
ok, got it. wvdialconf wasn’t able to detect you modem. you have to prob your device. to do this, type
sudo modprobe usbserial vendor=0×19d2 product=0×fffd
then type
sudo wvdialconf
and finally dial
wvdial cdma
I hope you are connected.
if not connected then you can edit /etc/wvdial.conf file and paste these following lines.to edit type
sudo gedit /etc/wvdial.conf
and paste following lines to the file and save it.
[Modem0]
Modem = /dev/ttyUSB0
Baud = 230400
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
[Dialer cdma]
Username = waps
Password = waps
Phone = #777
Stupid Mode = 1
Inherits = Modem0
Now dial again. type sudo wvdial cdma
hope, this will help

#15 by shabuz - December 17th, 2008 at 17:50
@arifeen
Permission denied!!?? use sudo for dialing..
example: sudo wvdial cdma
What’s your OS? ubuntu (hardy heron)? make sure modem detection path is ok and you probed it correctly..

@ Ashif
centOS? i haven’t tested in centOS though it should work there too. ok. i’ll try to configure and let you know. (i’m extreme busy this week but i’ll try to update)
#19 by admin - May 9th, 2009 at 21:15
In ubuntu 8.10 you will notice that it’s unable to detect devices in /proc/bus/usb directory. That means its not mounting the usb device so what you have to do is
connect your modem then mount the usb. to do this type
mount -t usbfs none /proc/bus/usb
Now check if the USB device is detected properly
cat /proc/bus/usb/devices
Then everything is same.. follow the process as i wrote earlier (dont bother with mountdevsubfs.sh.sh file if you are using ubuntu 8.10).
Good luck
#20 by Gesun Azad - May 12th, 2009 at 16:55
hey I’m using 9.04 nd could you send me the settings to my e-mail address (gesunazad@hotmail.co.uk) nd i heard theres a application called whine or sth like dat that lets u run .exe files on ubuntu. Is it true?
#21 by admin - May 12th, 2009 at 21:56
Ya true…. using wine you can run .exe file in Linux. to do this, you have to install wine ( Personally I don’t like the idea of using wine in linux and wine doesn’t work properly also)
Anyway, in ubuntu 9.04 jaunty, first you have to install wvdial (as wvdial wasn’t shipped with this version as a built in package)
then open menu.lst file (you’ll find this file in /boot/grub/ directory) and after kernel information add this following line and save the file
usbserial.vendor=0×19d2 usbserial.product=0xfffd
Now edit wvdial.conf with proper info (instruction given in the main post) , You’ll be connected.

Bro, your blog helps me much. Thanks.
In your last post about configuring ZTE modem in 9.04 there may be a slip of hand in usbserial.vendor=0(×)19d2 usbserial.product=0xfffd point. It may confuse a new user if s/he use it by copy & paste. thanks again.
I am very interested in algorithm and programming. What should i start first?
Thanks.
