If the rules to tag specific USB interface numbers only apply on the PID, we'll
end up seeing that if the port has a parent with another PID, and that other
PID also has a rule, port will get tagged multiple times. Easier to see with an
example:
The ZTE MF637 (VID 0x19D2, PID 0x0121) had the following rules:
ATTRS{idProduct}=="0121", ENV{.MM_USBIFNUM}=="04", ENV{ID_MM_ZTE_PORT_TYPE_MODEM}="1"
ATTRS{idProduct}=="0121", ENV{.MM_USBIFNUM}=="01", ENV{ID_MM_ZTE_PORT_TYPE_AUX}="1"
In our ZTE rules we also have some for the device with PID 0x0002, like:
ATTRS{idProduct}=="0002", ENV{.MM_USBIFNUM}=="02", ENV{ID_MM_ZTE_PORT_TYPE_MODEM}="1"
ATTRS{idProduct}=="0002", ENV{.MM_USBIFNUM}=="04", ENV{ID_MM_ZTE_PORT_TYPE_AUX}="1"
And it seems that we can grab multiple PIDs from a single port, i.e. from the
parent objects in the hierarchy:
udevadm info -a -n /dev/ttyUSB4 | grep idProduct
ATTRS{idProduct}=="0121"
ATTRS{idProduct}=="0020"
ATTRS{idProduct}=="0002"
Where that 0x0002 idProduct is not from the modem, but from the EHCI Host
Controller (with idVendor 0x1d6b in my case).
So... we end up seeing that both set of rules will apply to the ports, and we
misleadingly get:
(ttyUSB3) type 'at' claimed by /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2

Which is wrong, as ttyUSB4 should have been our primary port, not ttyUSB2.
With this patch on, the rules apply only to the VID/PID pair, and we end up
getting what we really wanted:
(ttyUSB3) type 'at' claimed by /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2

When setting allowed modes, a ",2" crept into the MODODR command when
porting the plugin from 0.6. That shouldn't be there.
When getting allowed modes, 2 is UMTS preferred and 4 is GSM preferred,
which the previous code combined into only UMTS preferred.
We will not report 'CS' as a supported mode every time '2G' is supported. This
actually was forcing all plugins to handle a 'CS' fallback when they didn't have
CS-specific mode setup. So, to simplify things, we will only report 'CS' as
supported for those plugins which actually allow to select 'CS' mode (e.g. the
'wavecom' plugin).
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.
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'
