No IMEI discovery, one-way audio, no inbound

[Marco Gaiarin]

Finally i've managed to get a non-scrabled K3765 key, 'Vodafone'
branded.

I've connected to my PC, fired up the terminal and try an 'AT^CVOICE?',
and the key correctly reply with:

ati
Manufacturer: huawei
Model: K3765
Revision: 11.126.03.06.00
IMEI: XXXXXXXXXXXXXXX
+GCAP: +CGSM,+DS,+ES

at^cvoice
^CVOICE:0,8000,16,20


so seem voice-enabled. Then i've configured dongle.conf, but the first
strangeness: if i set IMSI and/or IMEI, seems that does not work.
If i set serial device, work.
Note that i've another USB2serial converter (that have ttyUSB0 and
ttyUSB1), used to control the inverter of my photovoltaic plant, so
could be that chan_dongle ''hang on'' the first two ttyUSBX port?
I've waited some minutes, anyway...


Second step: i've configured outbound in dialplan, call are placed but
there's one way audio: called hear nothing.


Third: inbound seems not work, eg, i can call the number, rings, but
asterisk (log&verb 99) receive nothing.

You're doing it wrong .. usually the dongle presents itself as 3 ttyUSBx devices ..

one being the dongle itself .. 

second being the audio

third being the data !

If you don't get 3 of them .. you should use usb_modeswitch to switch it to the right mode ! 

Enjoy and happy hollidays !

> try to use usb_modeswitch and get 12d1:1001 for your device...

Ahem, i've just installed usb-modeswitch, but what mean 'get
12d1:1001'?!

I see on /lib/udev/rules.d/40-usb_modeswitch.rules

# Huawei K3765
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1520", RUN+="usb_modeswitch '%b/%k'"

but really my K3765 is a:

Bus 001 Device 017: ID 12d1:1465 Huawei Technologies Co., Ltd.
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00

idProduct 0x1465
bcdDevice 0.00
iManufacturer 4 HUAWEI Technology
iProduct 3 HUAWEI Mobile
iSerial 0
bNumConfigurations 1
[...]

I've simply to add '1465' as a valid product code? Probbably it is
better to make a custom udev rule...

Ok, i've understood a little better how usb_modeswitch work...
effectively my /etc/usb_modeswitch.d/12d1:1520 contain:

DefaultVendor= 0x12d1
DefaultProduct=0x1520

TargetVendor= 0x12d1
TargetProduct= 0x1465

CheckSuccess=20

MessageContent="55534243123456780000000000000011062000000100000000000000000000"

so it is normal that appear as '0x12d1:0x1465', usb_modeswitch works.

Googling around i've found also:

http://www.nervous.it/lang/en-us/2010/06/huawei-k3765-and-fonera-20n/

and after doing:
echo "0x12d1 0x1465" > /sys/bus/usb-serial/drivers/option1/new_id

a new serial /dev/ttyUSB5 appears. Now using /dev/ttyUSB4 and
/dev/ttyUSB5 incoming calls seems to work (i've some dialplan trouble,
but it is another story...), or at least are seen by asterisk, while
outgoing one got only silence, and lead asterisk to trash the system
(load at 20-30).


What i'm missing?! Mu usb_modeswitch configuration is too old?


Thanks.

Works. usb_modeswitch seems to do the right thing:

The thing that i've not understood is why usb_modeswitch start two
time, one for 12d1:1520 and another time for 12d1:1465.

Still autodiscovery using IMEI/IMSI does not work, but if i set
manually in dongle.conf:
audio=/dev/ttyUSB3
data=/dev/ttyUSB4

works, incoming and outgoing. If i use /dev/ttyUSB2 for 'data', i got
one way audio and no incoming calls.


Still i'm seeking feedback on why IMEI/IMSI discovery does not work...

[Alejandro Donato]

PID 1001 in this dongles means only the modem mode is enabled.

usb_modeswitch is designed to set this mode up. I think is not a chan
problem, is a modeswitch issue.

Your output shows that your dongle is in CDROM emulation and mass
storage mode. Thats why you have so many ttyUSB devices. Modem mode is
enabled (can coexist with other modes) but autodiscovery cant find it.

Check usb_modeswitch doc to set up your dongle to modem only mode (PID
1001)

Still a bit confused. You mean that i need a 'MessageContent' string
that will ''port'' 12d1:1520 to 12d1:1001, instead that currect (plain
deban squeeze) configuration that lead to 12d1:1465?

I doubt i can find a MessageContent string on some docs, probably
google will be my friend...

OK, afer issuing a 'AT^U2DIAG=0' (and unplug and replug the dongle) i
got:

exactly product '1001' as expected, and usb_modeswitch does not
apply.

If i verify the port mode before and after:

AT^GETPORTMODE
^GETPORTMODE:TYPE:WCDMA:Qualcomm ,MDM:0,NDIS:1 ,DIAG:2,PCUI:3,CDROM:4,SD:5

AT^GETPORTMODE
^GETPORTMODE:TYPE:WCDMA:Qualcomm ,MDM:0 ,DIAG:1,PCUI:2

and now asterisk find the dongle with imei, as expected. Wonderful.


Another little question, really a doubt: i've unplugged and replgged
the dongle, so seems that the modification is persistent, but... i've
to set also 'u2diag=0' in dongle.conf? Does not matter?
