Description of problem: ModemManager does not detect my Sony Ericsson K750i cellphone connected via USB cable anymore. This is a fresh regression. Last known good build: ModemManager-0.3-4.git20100323.fc13.x86_64 First bad build: ModemManager-0.3-5.git20100331.fc13.x86_64 Version-Release number of selected component (if applicable): ModemManager-0.3-6.git20100331.fc13 NetworkManager-0.8.0-4.git20100325.fc13 udev-151-7.fc13.x86_64 kernel-2.6.33.1-19.fc13.x86_64 How reproducible: always Steps to Reproduce: 1. Connect SE K750i with a USB cable. 2. Try to use nm-applet to connect to the Internet with it. Actual results: Notice there's no mobile broadband connection offered in nm-applet's menu today. Expected results: NM should see my phone and offer a mobile broadband connection using it. Additional info: I built ModemManager from git source to find which commit broke the functionality. This is the first broken commit: commit 4d89b519b4c889859a84780a18dbb2f12c9a9438 Author: Dan Williams <dcbw> Date: Wed Mar 31 03:05:22 2010 -0700 core: don't advance to next plugin until needed

Good catch. Fixed upstream by: bac945a8e4c1176d75f6c7d6622a516f673aaf65 Thanks!
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 'version' of '13'. 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 prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I don't have F13 anymore to test and it works fine in F14 and F15.
