[ltp] Sierra Wireless EM7345 4G LTE

[Vincent Bernat]

Hi!

I am trying to make the LTE modem shipped with the second gen carbon X1
works. I have found the following thread saying that it should work:
 http://linux-thinkpad.10952.n7.nabble.com/2nd-gen-X1-carbon-3g-lte-Sierra-Wireless-EM7345-4G-LTE-td21094.html

However, I am unable to get any /dev/cdc* device.

[ 9358.677017] cdc_ncm 1-4:1.0: MAC-Address: ff:ff:ff:ff:ff:ff
[ 9358.677860] cdc_ncm 1-4:1.0 usb0: register 'cdc_ncm' at usb-0000:00:14.0-4, CDC NCM, ff:ff:ff:ff:ff:ff
[ 9358.678148] usbcore: registered new interface driver cdc_ncm
[ 9358.679842] usbcore: registered new interface driver cdc_wdm
[ 9358.680771] usbcore: registered new interface driver cdc_mbim

Linux zoro 3.15-rc8-amd64 #1 SMP Debian 3.15~rc8-1~exp1 (2014-06-03) x86_64 GNU/Linux

So, I suppose the problem is that cdc_ncm kicks first. How can I switch
to another mode? I have the usb0 interface:

8: usb0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

Thanks!
