That's not too hard, just plug it in. :-)

However you must have set cdc_acm in your kernel, or availabe as a module.
It happens on all my machines on kernels 4.8 and 4.9.
Now, all my kernel configs will differ a bit, but must have something
peculiar in common. Or you've received a totally different device.

Here's one config at http://webserver.djo.tudelft.nl/.config-4.8.1

Many options are inherited by 'make oldconfig' from version to version,
without me knowing what it all means. So maybe it's just a weird combination
of options then?
