p.s. i did
tazhw setup 3g-modem
but it can't find any 3g modems :(

I think you will need to install the package linux-dialup.

# tazpkg get-install linux-dialup

then

modprobe option

This should detect your 3G modem. Then to dial out, you could use wvdial,

# tazpkg get-install wvdial

You will need to create a dial up script for your provider, then run "wvdial scriptname" to connect.

"modprobe option" gives an error "module option not found"

in my system it get installed from linux-dialup, did you tazpkg get-install linux-dialup ?

I downloaded linux-dialup-2.6.30.6.tazpkg from repo and installed it properly.
But i can't see any ttyACM or ttyUSB deices. Gnome-PPP can't find modems too :(

Install usbutils.tazpkg
Run with 3g modem plugged in.

lsusb

Post the complete output.

@Sourcerer, while you are at it, also run:

uname -r

and check what kernel version you are running (rather, make sure it is 2.6.30).

It is 2.6.34, i'm using slitaz-cooking

Phew. It seems, i need newer versions of linux-dialup

:), exactly. Seems like you are running cooking, which means you will need the linux-dialup package from cooking. You could download it from the packages database, just make sure you select cooking from the option. Better way to do it is using System Tools --> Package Manager. You can also do it using the command line,

# tazpkg get-install linux-dialup

This will download and install the correct version for you. You may want to remove the package you already have installed before proceeding, although it shouldn't really affect it -- but you never know.

people! i love you! it works!

i have the same problem.

i use Huawei E620

i do modprobe, and i've got this message

==================================================
root@slitaz:/home/mine# modprobe option Huawei E620
insmod: cannot insert '/lib/modules/2.6.30.6-slitaz/kernel/drivers/usb/serial/option.ko.gz': unknown symbol in module
modprobe: failed to load module option: No such file or directory
==================================================

anyone can help me to solve this problem?
thanks

output of uname -a ?

@stopstock because the command is just: modprobe option

Not all 3G modems work well, even if option has the ability to import new product/vendor ID's (What shows in lsusb with a : between the numbers). I'm working on converting over the betavine connection manager beta 3 (used to be called vodafone connection manager) to help with this. Hopefully I'll have something for you guys soon (and I'll finally be back on SliTaz).

@Trixar_za - perhaps the sakis3g script is an alternative for slitaz - I did not have time to test it ... http://www.sakis3g.org/

@ernia -
i use slitaz stable
and this is the output of uname -a

Linux slitaz 2.6.30.6-slitaz #1 SMP Sun Mar 28 16:39:51 CEST 2010 i686 unknown

@kultex -
i just follow the instruction on http://doc.slitaz.org/en:guides:dialup
there is wrote - modprobe option (Huawei E220, E160g, Venus-VT12)

@trixar_za -
previously, my E620 is detected normaly on my slitaz.
and then I tried to change the display screen with sexy desktop, then i installed wbar, tint2, nitrogen, cairo-clock.
and now, my Huawei E220 that i normally use now cant detected on my slitaz too.

*im sorry for my bad english*

if there is nothing wrong with your system kultex is right, and the guide (written by Kultex if i remember well :-) ) reports the modem requiring modprobe option between parenthesis and not as a parameter to the module.
if modprobe option alone does not work too try to reinstall linux-dialup

tazpkg get-install linux-dialup --forced

@stopstock "modprobe option (Huawei E220, E160g, Venus-VT12)" means you have to do "modprobe option" for the Huawei E220, E160g etc (the 620 uses also the module option). But there exist also Huawei modems with other drivers - not for all you do "modprobe option" - see with "lsmod" if the module option is really loaded - it should look like this

Module                  Size  Used by
option                 24896  0 
usbserial              29576  1 option

and then plug in the modem and give the output of the last lines of "dmesg" - it should look like this (my e220)

@ernia,
i was, but reinstall linux dialup is not working.

@kultex,
i thought i must do Modprobe when i use another modem :lol:
thanks for the explanation

@ all, now i know why slitaz didnt recognize my E620.
slitaz detected my modem as CD-ROM.
and is there any usb ModeSwitch for slitaz?

*im sorry for my bad english*

there are two ways of switching the modem in Linux (but there are some modems like the E220, where the info is already in the kernel, so you do not nedd neither hal nore usb_modswitch)

first is hal with hal-info - second is usb_modswitch

Slitaz decided for hal with hal-info (did you install hal-info - because this normally is done by tazhw)

it might be that the the E620 is not in hal-info of 3.0 so perhaps you can try to download and install the cooking package manually - http://mirror.slitaz.org/packages/cooking/hal-info-20091130.tazpkg - it should not make any troubles

as hal is now deprecated, with functionality being merged into udev - see http://en.wikipedia.org/wiki/HAL_%28software%29 - the last hal-info is from 2009 - i think, it would be good to switch for new cooking to usb_modswitch

as soon as I have time, I will try the sakis3g script with integrated usb_modswitch......
