Huawei USB modem intermittently not detected: loop of "deferring support check"

[PrivateUser132781]

Binary package hint: network-manager

I'm running Karmic x64 on an Acer TravelMate 6292.

When I plug in my Huawei E172 USB HSPA modem, it sometimes shows up in Network Manager and other times not. I can sometimes fix it by unplugging and plugging in again (in another USB port). When it is not detected, I see the following in the syslog:

Same here (Ubuntu Lucid). Sometimes detected properly, sometimes not, and loops all the time with the "deferring support check".

same here, modem actually works (I am connected right now, using the Vodafone mobile connect application from betavine), only not in network-manager

mine is a Huawei k3565 rev 2

[Masurao (masurao)]

Same here. Huawei E1550 (E620) on Lucid.

I think this is a bug in the modem-manager. So as not to reboot each time the modem disappears, I wrote a little script:

#!/bin/sh

gksudo killall modem-manager

Once the process of modem-manager killed, network-manager restores it and everything is OK: modem is detected.

[Sundberg Pauli (susundberg)]

Also same here.

Huawei E1820 and fresh install with 10.04.

I use wvdial for the connection, so no idea about network manager problems..

[Luca Mina (luca-mina)]

Me too with Huawei e270 on Ubuntu Lucid, after I plug in it start infinitely with this loop:

Aug 16 22:09:47 ubuntu modem-manager: (ttyUSB0): re-checking support...
Aug 16 22:09:47 ubuntu modem-manager: (Huawei): (ttyUSB0) deferring support check
Aug 16 22:09:50 ubuntu modem-manager: (ttyUSB0): re-checking support...
Aug 16 22:09:50 ubuntu modem-manager: (Huawei): (ttyUSB0) deferring support check

I can see ttyUSB port only if I give:

sudo killall modem-manager

Same here on Maverick using Huawei k4505

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Also, please do not add new "me too" comments. It is sufficient to click the "This bug affects..." link at the top of the page.

[Mathieu Trudel-Lapierre (cyphermox)]

Could you guys please try to reproduce this issue in Natty or on a Oneiric Live CD?

[penalvch (penalvch)]

Eduard Grebe, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc4

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
