Hi Phillipe,
Based on the latest usb_modeswitch rules, some 3G dongles require
to modify the ofono rules to be supported correctly (tests done in India)

I think you are way too late with these changes. We are not using
plugins/udev.c for Huawei and ZTE device detection anymore. I fixed this
all up and plugins/udevng.c should do proper automatic detection.
Please check if this works properly for you or if you have problems.
Hi Marcel,
I just experienced a case where the automatic detection brings a
difference with the previous implementation.
Using the dongle ZTE MF190 (DefaultProduct= 0x0149 TargetProduct=
0x0124), udevng.c is assigning the modem port to ttyUSB3 whereas ttyUSB4
was assigned with the previous udev.c based on the previous ofono.rules.
In practice, the port com ttyUSB3 is not responsive (I checked also with
minicom) so we can't manage to connect a data call (see ofono logs in
attachment). Using the previous combination udev.c + ofono.rules, if
the modem port assigned to ttyUSB4 is responsive, we are however facing
with an other issue:
ofonod[23908]: plugins/zte.c:zte_post_online() 0x9e2a470
ofonod[23908]: Aux:> AT+CREG=?\r
ofonod[23908]: Aux:< \r\nOK\r\n
ofonod[23908]: Unable to initialize Network Registration
ofonod[23908]: src/network.c:netreg_remove() atom: 0x9e29cf0
So, we can't go ahead for the data call since the network is not
registered. But this is an other issue we would need to fix I guess
specifically for this dongle.
Here, I just wanted to raise a potential issue regarding the modem port
com assignment for ZTE dongles:
Indeed, according the previous ofono.rules, we were assigning ttyUSB4 as
modem port for 2 product Ids:
ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0121",
ENV{ID_USB_INTERFACE_NUM}=="04", ENV{OFONO_ZTE_TYPE}="modem"
ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0121",
ENV{ID_USB_INTERFACE_NUM}=="01", ENV{OFONO_ZTE_TYPE}="aux"
ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0124",
ENV{ID_USB_INTERFACE_NUM}=="04", ENV{OFONO_ZTE_TYPE}="modem"
ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0124",
ENV{ID_USB_INTERFACE_NUM}=="01", ENV{OFONO_ZTE_TYPE}="aux"
but looking to udevng.c and particularly the function 'setup_zte', the
modem port can't be assigned anymore to ttyUSB4.
static gboolean setup_zte(struct modem_info *modem)
{
...
if (g_strcmp0(info->number, "00") == 0)
qcdm = info->devnode;
else if (g_strcmp0(info->number, "01") == 0)
aux = info->devnode;
else if (g_strcmp0(info->number, "02") == 0)
mdm = info->devnode;
else if (g_strcmp0(info->number, "03") == 0)
mdm = info->devnode;
}
}
So, I wonder if the condition:
else if (g_strcmp0(info->number, "04") == 0)
is voluntarily missing or not.
it might be missing. What does usb-devices say and how many TTY is this
one actually creating. If it creates indeed 5 TTY and the fourth TTY is
on interface number 04, then yes this should be added.
The general rule for ZTE is that the modem interface is suppose to be on
the last interface. Not sure if this is always true, but with all my
devices it was. And we could still overwrite this with a udev rule if we
have to.

Marcel
Hi Marcel,
Actually, with this dongle, we have 6 TTY (usb0 -> usb5) and usb-devices
gives:
T: Bus=02 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 32 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=19d2 ProdID=0124 Rev=00.00
S: Manufacturer=ZTE,Incorporated
S: Product=ZTE WCDMA Technologies MSM
S: SerialNumber=P671A2TMED010000
C: #Ifs= 7 Cfg#= 1 Atr=e0 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 4 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 5 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 6 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
Now, ttyUSB5 is not responsive. So, for this particular dongle, the
modem interface won't be on the last interface. Anyway, as I'm just
looking to add the condition related to the interface number 04, it
doesn't really matter.
Regards,
Philippe.
