Description of problem:

modem-modeswitch lacks the necessary rules and content to handle many of
the modems that need switching.  usb_modeswitch is far more complete.

In particular, the current Verizon offering, the UM175, is not supported
by modem-modeswitch, either by rule or code.  Even if the correct
command is executed, the code fails to switch the device to modem mode
because it it doesn't use the right string.  usb_modeswitch handles it
perfectly.

modem-modeswitch has the right idea, but needs to be expanded, or should
simply be replaced by usb_modeswitch, since it works.

Version-Release number of selected component (if applicable):

udev-extras-20090226-0.5.20090302git.fc11.x86_64

How reproducible:

Very.

Steps to Reproduce:

Insert the device, and watch with udevadm.
  
Actual results:

The storage device is recognized, but the modem never switches on, even
if you run the command by hand.

Expected results:

The device should switch to modem mode.

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  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bug reports from releases that are no longer maintained.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 '11'.

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 11'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 11 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:

This has already happened upstream; modem-modeswitch has been removed
from udev and usb_modeswitch is the way to go.

Title:
  Needs usb_modeswitch rule for UM175 (Verizon/Alltel 3G Modem)

Status in udev:
  Fix Released
Status in udev package in Ubuntu:
  Won't Fix

Bug description:
  As noted in Bug 328309, we need a udev rule for the UM175.  This is
  Verizon's current 3G modem
  (http://shop.verizonwireless.com/?id=Verizon+Wireless+UM175+USB+Modem+USB%20Modem).

  My (current, but see below) rule is:

  SUBSYSTEM=="usb", ATTR{idProduct}="3b03", ATTR{idVendor}=="106c",
  RUN+="/usr/local/sbin/usb_modeswitch"

  having previously configured /etc/usb_modeswitch.  I understand that
  the new udev code uses modem-modeswitch, but we still need a udev rule
  to invoke a switcher for this modem.  Accordingly, I replaced my rule
  with:

  ATTRS{idVendor}=="106c", ATTRS{idProduct}=="3b03", RUN+="modem-
  modeswitch -v 0x%s{idVendor} -p 0x%s{idProduct} -t option-zerocd"

  but that appears NOT to work (see below).

  Perhaps someone should go through the current usb_modeswitch.conf file
  and generate udev rules for the missing {idVendor,idProduct}-pairs
  (q.v., http://www.mail-archive.com/ubuntu-devel-
  discuss at lists.ubuntu.com/msg08733.html)?  And modem-modeswitch should
  be modified to handle more mode switching strings than the one
  hardcoded into it, or replaced by the more functional usb_modeswitch.
