Hello there!
First of all, I have really really tried the solutions in the Wiki to connect a USB 3G Modem (all of them). First, when I was with Netctl, and now, with NetworkManager.
I tried with wvdial, and then I just followed this https://wiki.archlinux.org/index.php/3G … pppd_alone
Then I followed https://wiki.archlinux.org/index.php/USB_3G_Modem
When I connect my device and do "lsusb" I get this:
Bus 003 Device 006: ID 12d1:1506 Huawei Technologies Co., Ltd. Modem/Networkcard
Which means, that Udev is automatically switching the mode of the Modem.
But, somehow, NetworkManager is not giving me a way to connect to my device.
I installed ModemManager and its active and running ( I checked this with "$ systemctl status ModemManager.service")
Same with NetworkManager.service
The last thing I tried was "forcing" the connection adding a Network Connection (Mobile Broadband). But when a I connect the device in another machine
with Debian, NetworkManager just recognize it and then, let you add the connection.
This is what dmesg is giving to me:

EDIT: have also looked this problem in the forum, but any post seems to have the same problem.
Thanks in advance.
