Bug 1347373

In Fedora 24 my device (E3372s-153) does not switch at work in any kind. Other USB modem (E173s-1) does not work too. Unhopefully, old option i225 is not working, so this appears to be could more general problem.

System is upgraded to current.


P.S. I observer, that in Fedora 23, switching of this modem is slighty weird. Just after machine start modem appeared, after switching, as legacy PPP modem (serial device). After restart, it switched to MBIM mode (USB Ethernet).

I've reported this bug against "pre-release" F24. Now I'm on offical F24 and the behavior slightly changed - when I plug it in, it mounts as mass storage device and Gnome gives me an option to auto-run included software. This behavior is also wrong.

I can confirm that this bug is still present in F24 (release). My Huawei E3131 (12d1:1f01) is detected as USB CD-ROM drive, and I have to modeswitch it manually using "usb_modeswitch -J -v 0x12d1 -p0x1f01" to get it to work as a modem.

Here's the output:

The modem worked fine and was automatically modeswitched with Fedora 23.

I would like to confirm this problem for Huawei E3131 modem:

Bus 001 Device 005: ID 12d1:1506 Huawei Technologies Co., Ltd. Modem/Networkcard

It happend automatically before upgrade to F23.

For me it looks as udevd/systemd-related problem, not a usb_modeswitch fault. The configuration for my modem exists in /etc/usb_modeswitch.d/

I can confirm that this bug in F24 (release). My Huawei 12d1:15e7 is detected as USB CD-ROM drive, and I have to modeswitch it manually using "usb_modeswitch -J -v 0x12d1 -p0x15e7" to get it to work as a modem. It happend automatically before upgrade to F23.

Today's upgrade of systemd/udev to version 229-9 (Fedora 24) solved the issue for me.

Not for me :-( 
I still have to switch mode manually.

229-9.f24 did not fix it for me either :-(

Huawei E3372 aka T-Mobile Speedstick LTE V, switching only works via
# usb_modeswitch -J -v 12d1 -p 14fe

Nor sure if relevant, but I think udev/systemd calls usb_modeswitch wrong?

Looks like recent update solved the issue. Unfortunately I don't remember what has been updated, didn't save the dnf's output.

It's most likely:
https://bodhi.fedoraproject.org/updates/FEDORA-2016-494a721a73

Fixes switching on E3372 for me.

I tried the updates you mention, and now all memory cards in my Huawei smartphone are no longer recognised as usb storage, but get modeswitched. Reverting to stock F24 solves the problem immediately, which is the proof that the faulty behaviour is introduced by the patches mentioned in Comment 11.

As this bug is about Huawei broadband modems not getting mode switched and your (possible) regression is about Huawei smartphone storage devices, that falsely getting mode switched, I would suggest filing a separate bug report.

I added a comment here, hope this helps!

This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '24'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
