Hi,
I'm trying to use a Raspbery Pi 3 with OpenWrt + a Huawei E5785-331mobile hotspot as residential internet connection. It works quite nice with a Wifi Brdige from the hotspot to the Pi. However I'd prefer to use the USB teathering feature of the hotsport. I tried to follow this article to make the hotspot to switch it's mode but accourding to the log output this is not working. It looks like the mode is switched several times until usbmod does not know the ID any more.
root@OpenWrt:~# dmesg | grep usb
