OS: balenaOS 2.38.3+rev2
We have an UBlox LTE modem in our device that we have been using for a while. It appear to the system as a RNDIS ethernet interface so everything should just work out of the box. After upgrading to BalenaOS 2.38.3, that device stopped coming up on boot. NetworkManager says is not managed and trying to set it to be managed by NetworkManager results in an error saying it’s strictly unmanaged.
After searching around, I found this thread that seems to have a solution: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1638842 <- comment #6 .
I confirmed that this does work but required modifications in the filesystem on the HostOS side. Is there a way to achieve the same results via DBUS or another method?
