--- Comment #2 from Andrea Turrini 2014-06-05 07:15:49 UTC ---
I was playing with Virtualbox trying to reproduce the issue, so I connected the
phone via the usb cable and then attaching/detaching the device to the virtual
machine (while keeping it physically connected).
If I do this, when I detach the device, then it works in the real system.
/var/log/messages contains the following lines, starting from the previous
failed status as in the other logs:

So, it seems something related to the kernel, not ModemManager.
