EM7455 - Unable to connect using linux on Thinkpad X1C5

Hi,

I’ve been trying to get the EM7455 in my 5th generation X1 Carbon working on Linux (Nixos) for the last few days but I haven’t had much luck. The card worked perfectly in the stock Windows 10 before I switched over to Linux. I’m using ModemManager 1.6.2, Libmbim 1.14.0 and Libqmi 1.16.0 on Kernel 4.9.13. I’ve put the output of a bunch of commands below but to be honest, I don’t really know what I’m doing! any help would be greatly appreciated!

The ModemManager mailing list here is probably a better place to ask:
https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel

Anyway, I’d suggest you try to build and install ModemManager from git master and retry. This could be a “FCC auth” issue, and there are some fixes related to that that haven’t been released in any 1.6.x yet.
