I didn't know this, thanks!

Unfortunately, that is not necessarily the case.
The device allows to connect "everything".

But it is an important point, that the time printed by
"blame" might not be the relevant information for me.
I'll try to find the real culprits in boot time, which
might be something else than NM or MM.

modemmanager 1.10.0 (-1)
network-manager 1.14.4 (-4)

Not so bad versions :-)
