+ adding ofono mailinglist as it may be of interest

Point is, that I am trying to run the u-blox on ofono+connman and 
had/have some questions regarding the setup.
I compiled the git version of the ofono for a freescale vf610 board with 
an onboard ublox usb adapter and got quite far.

A manual setup on pppd+peer+provider+chat script gave me a clean 
internet connection.

Now I want to integrate that with ofono/connman. I got ofono finding the 
module, advertise it as a cellular technology to connman, but no service 
is showing up.

I will go on setting up the umts high throughput profile.

So the rest of the story can be found below!

@Dragos:
without any changes, I got
lsusb:
1546:1146 U-Blox AG (which is high performance?)

online modem runs without any complains, but without any changes
root(a)colibri-vf:~/test# ./online-modem
Setting modem /ublox_0 online...
