To explicitly answer your earlier questions: "You're missing here the cdc-wdm ports to talk QMI. Is this a self-compiled kernel? Is the cdc-wdm driver enabled in the build?"
My original attempt was using the current Arch kernel, 4.4.5, from the stock package. I checked /proc/config.gz and the WDM option was listed as a module, the CDC options were also compiled in. I did not check the /proc/config.gz with kernel-mainline 4.5 to see if any config options had changed that might explain the increased functionality in 4.5. - Steven On Wed, Mar 23, 2016 at 3:06 AM, Steven Pease <spe...@suitabletech.com> wrote: > Hi Aleksander, > I used Arch Build System to grab the existing package builds of libqmi and > ModemManager and built 1.14 and 1.5.990 respectively from > https://www.freedesktop.org/software/.
