Hi everyone..
i am using slackware13 x64 on a dell vostro laptop..i use a Huawei EC325 wireless modem to access the internet.. slackware detects it as E620 anyway but i am having a weird problem.. just 2 days back i went through all blogs regarding connecting to internet with an usb modem and did the necessary..ie
1. installed wvstreams and wvdial packages obtained from slackbuilds.org
2. modified /etc/wvdial.conf as below
bash-3.1# nano /etc/wvdial.conf
[Dialer Defaults]
Modem = /dev/ttyUSB0
Modem Type = Analog Modem
ISDN = 0
Baud = 9600
SetVolume = 0
Dial Command = ATDT
init1 = ATZ
init2=AT+CRM=1
FlowControl = Hardware (CRTSCTS)
[Dialer bsnl]
Username = 165
Password = 165
Phone = #777
Stupid Mode = 1
Auto DNS = 1

bsnl is the ISP in my region...
3.after giving the command 'wvdial bsnl' i was connected , everything went fine.. i got connected instantly...the surfing speed was good...
but after rebooting i tried to connect back but here is the outcome
bash-3.1#wvdial bsnl
--> WvDial: Internet dialer version 1.60
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
4. lsusb still recognizes my modem
bash-3.1# lsusb

Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
5. dmesg also shows it
bash-3.1# dmesg
usb 5-1: new full speed USB device using uhci_hcd and address 5
hub 5-0:1.0: unable to enumerate USB device on port 1
usb 5-1: new full speed USB device using uhci_hcd and address 6

usb-storage: probe of 5-1:1.0 failed with error -5
usb-storage: probe of 5-1:1.1 failed with error -5

i have tried various alternate locations for the Modem=/dev/ttyUSB0 by /dev/ttyUSB1 2 3 but it still doesn't work the same error everytime...

for this i need to go back to windows everytime i need to access the internet which is very irritating... so plz help

thanks in advance

someone suggest something.....please

Try as root "modprobe option". It doesn't seem to be detecting the USB modem properly. I have a Huawei E220 and this shows up in dmesg when it creates the ttyUSB devices:

Edit: also, you can check the presence of any ttyUSB devices with "ls -l /dev/ttyUSB*".

thank u rg3...the problem was that a highly intellectual person had blacklisted option .....so dmesg cud not detect the modem properly.... thanks a lot
