I think the rndis_host USB driver might emit a warning in the dmesg, but disabling the driver wouldn't be a good idea. The TP-Link MR6400 V1 LTE modem and also some ZTE modems integrated in routers do use this protocol. We may also distinguish between these cases and devices you might plug in - as they pose different risk levels. Enrico
