Hello, I have installed Armbian Debian Stretch Next (mainline kernel) on my Odroid C2 and updated to newest version(apt update & apt upgrade). Everything works fine except USB ports.   I have USB LTE modem which is not recognized. I have tried "lsusb -v" but with this modem not works. But when I connect USB keyboard first then "lsusb -v" and next I connect LTE modem and type "lsusb -v" then it's works.   I also tried connecting USB LTE modem before Odroid C
