I believe it should work with a v4.8 kernel. But the modem is fully
configurable.  Maybe it is using an identity we don't know?

What's the output of "lsusb -v"? Feel free to remove irrelevant devices
and serial numbers etc.  I'm primarily interested in the modem device ID
and which functions it is configured for (serial, qmi, mbim, etc).
