Re: udev doesn't recognize my gsm dongle

Hello Dan,

I took some time to try what you asked me. 

Just to sum up.
I use NetworkManager 7 to connect my GSM dongle. When I launch NetworkManager nm-system-settings and modem-manager I got those messages when I plug my device :

** Message: (ttyUSB1) opening serial device...

I changed the lines as you asked me too and there are the logs :

I don't see any problem there. When I use the nm-tool command no device is seen. 
I got it working modifying the LIB_UDEV flag. But it only works when I plug my device when the board has done all its init. 
So if I let it plugged at boot it is not recognized and I can use it.

Thanks for your input !
