Many tests done and the system behavior is very bad when network manager and modem manager running, after ejecting the created CDROM. Partially freeze on terminal, cannot open a new terminal or complete freeze of the system. I can understand 'no connection' but 'loosing' the system is a real 'bug'.
After a clean install of Ubuntu 9.10 Alpha 4 my best way to connect with ZTE MF636 modem: 0- boot without the modem, wait for the system to load 1- stop network manager 2- check that wvdial is not running (no process) 3- find process number of modem-manager 4- kill modem-manager 5- attach modem 6- check lsusb: 19d2:2000 (CDROM) 7- wait and eject CDROM created (sr0) 8- check again lsusb: 19d2:0031 (modem) 9- check creation of /dev/ttyUSB0-1-2 a- connect using wvdial and port /dev/ttyUSB2 b- checked that the connection done: valid IP, DNS ******* code g...@kka4:~$ sudo /etc/init.d/NetworkManager stop [sudo] password for g: * Stopping network connection manager NetworkManager [ OK ] g...@kka4:~$ ps -A | grep wvdial g...@kka4:~$ ps -A | grep modem 1494 ? 00:00:00 modem-manager g...@kka4:~$ sudo kill 1494 g...@kka4:~$ ps -A | grep modem g...@kka4:~$ lsusb Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 004: ID 19d2:2000 ONDA Communication S.p.A.
