It shows the modem is using regular AT commands, when it should really be using QMI instead. What is "lsusb -v -d 1bc7:1201" for this device? The problem appears to be: Jan 1 20:48:44 linaro-gnome kernel: [ 10.661323] qmi_wwan 1-2.1:1.5: bogus CDC Union: master=0, slave=0 Jan 1 20:48:44 linaro-gnome kernel: [ 10.661409] qmi_wwan: probe of 1-2.1:1.5 failed with error -1 Bjorn/Carl/others would probably know more about why the probe fails for this device. But if you could grab the lsusb -v output I asked for above, that would help figure it out.
