Nozomi devices are old Option NV CardBus devices with the ttys (nozX)
hanging directly off the PCI device. We need to read the vendor and
product IDs off them too. It appears that udev screws up the ID_MODEL_ID
field (at least on F17, its set to the device path and not the PCI ID)
so just skip looking at the TTY itself and read the PCI parent, where
we're 100% sure to find the PCI IDs we want.
This patch adds a 'hotplugged' flag to MMBaseModem to indicate if a
modem is newly plugged in. A plugin can use this information to
determine if, for example, the modem needs to be soft reset using the
ATZ command.
Dan Williams <dcbw@redhat.com> contributed the idea of implementation.
Both the ModemManager daemon and the mmcli will now include `libmm-glib.h' only.
We also handle two new special `_LIBMM_INSIDE_MM' and `LIBMM_INSIDE_MMCLI'
symbols, which if included before the `libmm-glib.h' library allow us to:
* Don't include the libmm-glib high level API in the ModemManager daemon, as
the object names would clash with those in the core.
* Define some of the methods of helper objects to be included only if compiling
ModemManager daemon or the mmcli.
Don't rely only in the first grabbed port to get VID/PID. Some modems, e.g.
Huawei E367, won't report a proper VID in the cdc-wdm port, which is the first
one probed.
We'll try to cope with getting devices being reported in either 'usb' or
'usbmisc', trying to avoid the need of checking kernel version during runtime.
Different ports of the same modem may get handled by different drivers. We
therefore need to provide a list of drivers (new `Modem.Drivers' property with
signature 'as') instead of just one (removed `Modem.Driver' property with
signature 's').
$ sudo mmcli -m 0 | grep drivers
| drivers: 'qcserial, qmi_wwan'
Before this, we only exported the modem to DBus when all ports were organized,
in order to make sure that we select as primary port the one we really want and
not the first AT port grabbed. Given that to get all the ports organized we also
needed to wait to get all the ports grabbed, we can now also defer the creation
of the modem object until all the ports get grabbed. This allows us to create
different types of objects based on the ports available (e.g. we can now create
QMI-supported modem objects if we see a QMI port around).
