This shows that the first altsetting is active when there is no driver.
That's good.  It supports the assumptions we made for cdc_mbim/cdc_ncm
probing.

And this shows that it worked.  The cdc_ncm driver is active and has
configured the data interface for NCM.

You should retry MM with this setup.  It should work.
