Network device + DM Port (No separate Modem and GPS/Glonass ports)
my long post kind of summary of my experiments for last 2 days…
I could tr anything on OpenWrt/Ubuntu/Windows. But looks like for now I have only idea with old FW version
As i know, only the tool setusbcomp.exe from distributor can fix the issue
But you can also try old firmware to see if there is any luck
