There's no entry in the qcserial kernel driver for the AT ports in that module. A couple of weeks ago I sent for inclusion the EM9191 TTY exposed during firmware upgrade, which has its own vid:pid, but I didn't even try to add the missing entries for the TTYs in normal non-upgrade mode. Patches to the kernel welcome :) It should really be a one-liner patch. P.S. libqmi/qmi-firmware-update git master implements support for upgrading firmware on this module just fine -- Aleksander https://aleksander.es
