Verizon 3G USB unable to reconnect

[tekstr1der]

Binary package hint: network-manager

Verizon UM150 connects as expected the FIRST time. Subsequent attempts to connect during session fail.

STR:

1) insert USB modem device
2) connect via network manager applet
3) disconnect via network manager applet
4) remove device
5) insert device
6) attempt to connect via network manager applet

RESULT:

Unable to connect on any subsequent attempt. notify-osd states offline - disconnected

WORKAROUND:

Simply killing modem-manager is enough to work around this issue. It automatically re-spawns and the connection can then be established.

Also, I tried to obtain a modemmanager debug log for this. However, after stopping the network and killing modem-manager, it still restarts automatically and I don't have the opportunity to start it with the --debug option.

The device no longer connects initially either. Need to killall modem-manager first, then it will connect.

Have resolved this issue for me. My 3G modem connects initially without killing modemmanager first and subsequent disconnect/connects during user session work as expected. Thanks!

Hello.
I have a 3g modem zte mf100, and am experiencing exactly the same issues as above.
When I plug the modem, I have to kill modem-manager, in order that my connection in network manager becomes available (or reboot computer).
Details:
Ubuntu 9.10 (karmic)
kernel: 2.6.31-17-generic
network-manager: 0.8~rc2~git.20100108t192339.a74e2cf
modemmanager:0.2.git.20100112t172936.a4fee86

Should I open a new bug for this?
I am sure it is the same issue as above.
Thanks.
Bogdan
