[SOLVED --see below]

A "Vodafone internet key" (modem usb Huawei E172) comes to me last week, and I am trying since then to make it work on my fedora 7, (64 bits, on a Toshiba satellite P200 17D).
I installed the Linux driver from here:
https://forge.vodafonebetavine.net/frs/?group_id=12
(version 1.99.17)
When I plug the key and then start the program "vodafone-mobile-connect-card-driver-for-linux", it tells me that it cannot use or write /dev/ttyUSB0. If I change the permissions (that change don't last when I unplug the key) on that file to use it, the program fails to start but remains idle on memory and I need to kill it together with the process from python-twisted. In any case, I cannot reach the configuration panel.
I know that this driver works with older usb modems from vodafone, but there is anyone who know how to use this new system on Linux? Or any other alternative? I tried to use kppp, but I don't know what to put on the different options...
I don't have any other internet connection at this moment.
Thanks!

I don't know who works on the Vodafone Mobile Connection Card Driver for Linux project but they deserve serious kudos for providing structured and easily readable documentation. Did you check out /usr/share/doc/vodafone-mobile-connect-card-driver-for-linux-*/guide/install/x120.html#AEN125 ?

Thanks for your answer. In fact, that document solves the permission problems... but the program don't work.
If I run in debug mode, I obtain the following

I can't understand those messages. Any hint?
Thanks!

Dunno, but rereading the release log for 1.99.17 it states "Fedora 8 supported, Fedora 7 support not continued". Fedora itself supports one release before current, so you could ask in https://forge.vodafonebetavine.net/f...hp?forum_id=20 if it's not too much trouble. OTOH with Fedora it's good practice to stay upgraded with current so maybe you could "just" upgrade to 8. FWIW and while it's no guarantee I did upgrade ("if it ain't broken let's try and break it") one machine last year from FC6 to F7 to F8. All done within a few hours and w/o showstopping glitches.

Finally, I installed fedora 8 and now everything is running!

Can anyone help me figure out what kernel module is related to this USB modem?

Because I can see the modem with lsusb, but can't query it on /dev/ttyUSB0

Is there a kernel driver embedded in the Vodafone file from betavine forge?

Some of these modems start up as a "CD" with the windows drivers being presented to windows for windows to load them.

Some distros cope with this automatically now, others don't (and you haven't told us yours).

You may need a utility called usb_modeswitch to switch the dongle to "modem mode".
Search for usb_modeswitch, download & install it.

Once my dongle is plugged in I need this "magic code":
The numbers after the v and p parameters refer to the vendor and product ID numbers listed by lsusb for my modem (A Huawei E169G)
If you are in the mood, you can write a udev rule to make this happen automatically when the dongle is plugged in.
