NetworkManager with ModemManager and 3G Ericsson f3507g

[bizonek]

Hi

I got issue with NetworkManager with ModemManager and 3G Ericsson f3507g card. It's work on wvdial but not stable. On NetworkManager I cannoct enable this device. I think problem is with sending AT command: ATZ (f3507g is not recognize this command).

My friend got the same laptop but installed Ubuntu and this device working. I use VPN and many WLAN connection so need this in one tool. Can sameone help ?

I was right, the plugin ericsson-mbm.so cannot connect to device as /dev/ttyACM*. After ModemManager start, use only generic.so, cinterion.so and iridium.so to connect with /dev/ttyACM*.

This is not a solution, only workaround

After emerge with this patch, NetworkManager connect to device and get IP.
Problem is with a PIN, but wvdial solve this issue by:

Back to the subject.

Today after update, I have shutdown NetworkManager and kill modemmanager. Put debug mode on ModemManager and use modem cdc-ether in kernel module, use Ericsson MBM plugin.
Using nm-tool show "cdc-ether" (befor update he show "cdc-acm"). So the problem is with module ??
After restart he start using "cdc-acm" and 3G card is not working again.

How tell ModemManager to use "cdc-ether" module not "cdc-acm" (if I remove module cdc-acm kernel cannot find device).

I have no luck keeping ModemManager running with my 3G Modem. I usually end up using KPPP. Or even gnome-ppp.
