[opensuse] Gnome PPP: Can not open Modem

1. I've installed a dedicated driver included with a Mobile Broadband USB modem D-50 from CMOTECH CDMA Technologies on openSUSE 10.3/Gnome 2.20.0, both on a stationay i386 PC and on a x86_64 workstation. This adds a new entry
crw-rw---- 1 root uucp 166, 0 2008-03-14 02:17 /dev/ttyACM0
2. Thereafter I've tried to configure the modem with YaST>Network devices> Modem:
CMOTECH CDMA Technologies
• Device name: modem0
• Mode: unknown
• Startet manually
Modem device: /dev/ttyACM0
Set phone no #xxx, userID and password
External Firewall zone
3. Third, I tried to dial up with Gnome PPP (gnome-ppp-0.3.23-0.pm.2)
entered username, password and phone number on the first widget
"Detect" on the setup widget warned "No modem was found on your system"
manually selected type: USB modem, but still only devices /dev/modem and /dev/ttySx were available on the list.
Therefore I did manually try to enter /dev/ttyACM0 as device, then closed this widget
and tried to "connect" from the startup widget, but it warned "cannot open modem".
The "Connection Log" looks as follows:
--> Ignoring malformed input line: ";Do NOT edit this file by hand!"
--> 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 have also tried to login as root and run Gnome PPP, but no connection and the same error
4. I have however succeeded to connect as root in a terminal with this commmand:
# wvdial --config wvdialice.conf
where the config file "wvdialice.conf" contains
[Dialer Defaults]
Modem = /dev/ttyACM0
Carrier Check = no
Stupid Mode= yes
Phone = #xxx
Username = yyyy
Password = zzzz
New PPPD = yes
Running the same command as normal user, results in the same warning output as the Gnome PPP log file above, and no connection.
Any suggestion why Gnome PPP doesn't find or can not open the modem?
(neither "chmod 777 /dev/ttyACM0" does work)
Cheers,
