Ah!

- From my notes, in "/etc/permissions.local" I did:

/usr/bin/wvdial root.dialout 4750

Now I also added that line

I forgot to mention that you need to run:

SuSEconfig --module permissions

to apply the change. It will run automatically every day, anyhow: if you don't edit permissions.local it would change back to the default permissions.



I think that was all I needed. No, I added my user to group dialout, too.

My user was already added to the three groups: dialout, video, users


Please copy here the exact error that a wvdial session prints.

Did a reboot, but still this doesn't work running the dialup command as normal user:

~ > wvdial --config wvdialice.conf
--> WvDial: Internet dialer version 1.56 (abuild@balli)
--> Cannot open /dev/ttyACM0: Device or resource busy
--> Cannot open /dev/ttyACM0: Device or resource busy
--> Cannot open /dev/ttyACM0: Device or resource busy

I would try accessing the modem with minicom, but I'm unsure because of what you add later.


I can add that there also may be some bug related to the CDMA USB modem driver, because after disconnecting the modem and system restart, the /dev/ttyACM0 is disappeared and the driver has to be reinstalled (as root) and with output as follows:

Ah, not a plain modem, then, with a proprietary driver.


# ./RDEVCHG

RDEVCHG Linux Version : 1.0
Please, Wait!
Bus 001 Device 004: ID 16d8:680a
....
Success SwitchMode.
*** stack smashing detected ***: ./RDEVCHG terminated

I suppose you don't need reinstalling the driver, but loading the pertinent module.

My provider's support has told me that the Gnome PPP launcher does work with this modem on Ubuntu, and this is also my main purpose on openSUSE.

However, I've never used this type of modems, I don't have experience with them. Some one was asking about a similar modem not too long ago: search the archive, perhaps for the word CDMA, in the last 8 months at least.
