Hi,

in a Lenovo X1 Carbon Type FB20, using openSUSE 42.1, the EM7455 is 
unavailable, although:
 * a Linux 4.8 kernel is installed 
   (build here: https://build.opensuse.org/project/monitor/home:frispete:Kernel-current)
 * libmbim-1.14.0, libqmi-1.16.0, and ModemManager-1.6.0 are installed 
   (from the same repo)

The device is shown as follows:

T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=480 MxCh= 0
D:  Ver= 2.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1

I:  If#=13 Alt= 1 #EPs= 2 Cls=0a(data ) Sub=00 Prot=02 Driver=cdc_mbim

The cdc_mbim module gets loaded:

~# dmesg|grep mbim

[    6.377428] usbcore: registered new interface driver cdc_mbim

but the ModemManager can't talk to the device:
