Bug Description

au DATA07 / HUAWEI DATA07 is not recognized as a CDMA2000 1x modem.

Oct 25 01:32:23 fmv modem-manager[774]: <debug> [mm-serial-parsers.c:448] mm_serial_parser_v1_parse(): Got failure code 100: Unknown error
Oct 25 01:32:23 fmv modem-manager[774]: <warn> [mm-plugin-base.c:856] real_handle_probe_response(): Couldn't probe for capabilities, probably not a GSM or CDMA modem
full debug output of modem-manager is attached in the comment #2.

au(by KDDI) is a mobile carrier who has CDMA2000 1x EV-DO network.
au DATA07 / HUAWEI DATA07 is a USB modem for their network.
# from the specification above,
# DATA07 seems capable of up to CDMA2000 1x EV-DO MC-Rev.A.

usb-modeswitch-data already has the rule for it and properly changes device ID from 12d1:1446 to 12d1:1506(modem).

# Huawei, newer modems
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1446", RUN+="usb_modeswitch '%b/%k'"

In contrast to modem-manager, wvdial can dialup with the modem.
output of wvidalconf command is attached in the comment #3.
generated wvdial.conf is attached in the comment 4.

The patch attached adds an additional check for CDMA capabilities in ATI replies, which should trigger the detection of this modem as a CDMA modem.

Are you able to apply this patch (in a 0.6 release) and retry?


Nobuto Murata (nobuto) wrote :

Thank you for the patch. But unfortunately I cannot build it.

I patched the debdiff below to the quantal package

Then I faced the error:
mm-plugin-base.c:458:19: error: 'MM_PLUGIN_BASE_PORT_CAP_IS707A' undeclared here (not in a function)

full build log is available here:

Are there any missing piece that I should do?

Sorry, should have compiled the patch here before sending it :-)

I uploaded a newer version of the patch that should compile correctly.

I will attach debug log of modemmanager with your patch.
Indeed the patch changes output of the modem and it will be shown up in NetworkManager applet, but it's as Offline state.

I will also check debug log of NetworkManager.

logs with --log-level=DEBUG of NetworkManager and modemmanager.

When plugged-in.

Note to after-clicking-enable-mobile.log:
Though "Mobile Broadband" entry remains "not enabled", I have clicked "au(KDDI) connection" on Oct 31 00:26:12. but taking no effect on indicator status.

Seems to work correctly for me with the patch (in fact I'm uploading this to Raring now). Do you mean that the modem can't successfully connect to the au(KDDI) network? I unfortunately can't really test this -- I'm in Canada, so I won't be able to connect to the japanese network.

Jonathan, you nominated this to be SRUed to Precise. Is this really required? Can you do the necessary paperwork (updating the bug description) for the SRU process?

Hi Mathieu,

I tested the patch a while ago, then it enabled the "Mobile Broadband" section shown up.
But unfortunately the section was grayout and I still cannot dialup to the au(KDDI) network.

I will test again against raring.

Mathieu: could you get some nice debug logs for a full session with this modem?

Nobuto Murata (nobuto) wrote :

I tried modemmanager on raring daily build.

It sounds like my problem can be divided into two parts.
1. not recognized as CDMA2000 1x modem.
2. even if it has been recognized properly, I still cannot connect with it.

1st part seems resolved by including handle_data07_capabilities_probing.patch.
2nd part was turned out that actually a crash of modem-manager. So I filed it as a separate bug #1083659.

Aleksander, could you please add the patch upstream, as it is now also needed to progress on bug #1083659 ?

Pushed both to MM_06 and git master.

Nobuto MURATA: then you should be able to test the upstream PPA again tomorrow.
