Re: modem-manager: No-Plugins and networkmanager not able to detect modem device

[hong sheng <hong022011 gmail com>]

Hi Bin, 

I solved the problem and now the modem can do auto-connection. The original problem was caused by sid 0 re-signed to be sid 99 issue as posted in the website

https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/456612


Thank you very much for the help. One more confusing question, will networkmanager 8.0 always need modem-manager to manage modem or itself can do modem management if I just need connectivity rather than need sms or signal strength detection?

thanks

Hi Bin,

Thank you very much for the quick response. It solves my problems.

However, the follow up trouble I met is that the modem is not be able to be activated. The modem I am using has 4 ttyUSB ports. I think one of the port is used for modem while others are used for other purpose.  I am using a keyfile TestModem1 for auto-activating modem.


Could you please help me out on this issue? Also, if I want to specify the ttyUSB port, for example, force to use ttyUSB2, how can I set it in the keyfile (for my case, TestModem1 in the /usr/NetworkManager/system-connection)?


Again, thank you very much

Which distribution do you use?  Could check your
/usr/lib/ModemManager/ ? The plugins should be there.

you can get it from dmesg.
