Description Roland Pallai 2011-07-24 21:44:32 UTC
Description of problem:
I got E173s-1 from T-Mobile Hungary but NetworkManager didn't recognized it as a modem.

Udev in debug mode showed if usb_modeswitch failed:

Jul 24 22:04:00 daptop udevd-work[4009]: '/lib/udev/usb_modeswitch' (stderr) 'Error: getting the current configuration failed (error -110). Aborting.' 
Jul 24 22:04:00 daptop udevd-work[4009]: 'usb_modeswitch '/1-4:1.0'' returned with exitcode 1 

After a hard struggle I found that
 echo WaitBefore=3 >>/etc/usb_modeswitch.d/12d1:1c0b
perfectly fixes the problem. I didn't found any other solution from udev.

Version-Release number of selected component (if applicable):
usb_modeswitch-data-20110227-1.fc15.noarch

How reproducible:
always

Steps to Reproduce:
1. Plug-in Huawei E173s-1

Actual results:
NetworkManager nor ModemManager doesn't do/logs anything

Expected results:
NetworkManager should recognize the stick as a modem

Additional info:
I reported it into a forum topic too (more verbose):

I don't know yet if it is the same problem, but i also cannot normally use my HUAWEI/NOWAY E173s with F15 on my laptop.

The workaround is to power-off the laptop, plug the thing, power on and it is detected normally and correctly (as a modem). It does not allways connect but that is another issue.

Have you tried with F16 or F17 recently?

I have been able to use mine E173s-6 with F16 recent kernels.

At present mine works with F16 kernel 3.3.7-1.fc16.x86_64

There are still issues:
No reconect, the modem needs to be unplugged and replugged.
Sometimes the modem does not show up (rare), but unplugg and
replugg works.

I think this device is 90% functional now.

This message is a notice that Fedora 15 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 15. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

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

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 15 reached 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 to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

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.

The process we are following is described here:
