I's a long story.
Recently i buyed this modem but it runs only on Windows10 Machines "out of the box" without any drivers installed (Plug And Play).
I compiled Openwrt some days ago with the latest version together with Modemmanager (from github) but the modem will not recognized.
Other modems e.g. MC7455 work flawlessly with ModemManager
First my setup:
Openwrt Version: OpenWrt SNAPSHOT r11333-d3d06f1500 / LuCI Master (git-19.304.35036-4798b3f)
ModemManager Version;
/tmp$ mmcli -V
mmcli 1.10.6
