Description of problem:
Working kernel-2.6.27.7-134.fc10.i686 writes the following to the messages log when the modem is plugged in:

In the working kernel, a new device node is created: /dev/ttyACM0.


The new kernel-2.6.27.9-159.fc10.i686 writes this to messages instead:

Under the new kernel, the device nodes /dev/ttyUSB[0123] are created.  I'm not able to get the "dial-up" connection working with the new device nodes.  I tried modifying /etc/sysconfig/network-scripts/ifcfg-Verizon and /dev/wvdial.conf by hand to use /dev/ttyUSB0 as the modem device.  Attempting to bring up the connection simply hangs.

I'm not currently able to create a completely new modem connection because system-config-network crashes when I attempt to save.  I'm about to file a bug for that as well.  Please provide me with additional tests if you'd like more information.

I am seeing similar issues with kernel-2.6.27.9-159.fc10.i686, here is the message I get when Network Manager attempts to initialize my PANTECH UM150 USB Modem:

I have noticed this exact same issue.  In message I see this when I try to connect:

an 15 11:11:55 icarus NetworkManager: <info>  Activation (ttyUSB0) Stage 1 of 5 (Device Prepare) started...

Jan 15 11:12:06 icarus NetworkManager: nm_system_device_flush_ip4_addresses_with_iface: assertion `iface_idx >= 0' faile

To me this is clear that NM is no longer able to init the device with an ATDT.  To test, I tried minicom configured for /dev/ttyUSB0 and was unable to init the modem.  When I switched to using /dev/ttyUSB1, the device is able to init.

As a workaround, I have changed my HAL rules in /usr/share/hal/fdi/information/10freedesktop/10-modem.fdi.  The workaround is on line 181.

Change:
<match key="@info.parent:usb.interface.number" int="0">
To:
<match key="@info.parent:usb.interface.number" int="1">

This instructs HAL and subsequently NM to use /dev/ttyUSB1 as its dialout device.  It would appear in the newer kernel that the device enumeration is different causing the problem.
Comment 3 Brent Holden 2009-01-15 20:14:42 UTC 
I should have added to my original comment that the device in question is a PANTECH UM150 USB modem.
Comment 4 Pete Zaitcev 2009-01-17 00:53:43 UTC 
The Pantech 106c/3711 was added by Dan Williams:

commit 8b6346ec899713a90890c9e832f7eff91ea73504
Author: Dan Williams <dcbw>
Date:   Fri Oct 10 06:41:16 2008 -0400

    USB: option: add Pantech cards
    
    Add some Pantech mobile broadband IDs.

Perhaps UM150 is different from the two other Pantechs and should be
removed from option.c.
Comment 5 Dan Williams 2009-01-20 18:01:19 UTC 
The patch for option.c is correct, it's that HAL/NetworkManager aren't correctly detecting which TTY of the device is actually the modem TTY.  This is statically set now, but soon will be automatically detected through udev probing of serial ports of hardware driven by known mobile broadband drivers.
Comment 6 Stuart R. Kirk 2009-01-25 21:01:36 UTC 
Camping on to this BZ.  I have noticed the exact same behavior.  The modification to HAL did, also, work on my system.
Comment 7 Andrew Hecox 2009-02-04 12:27:30 UTC 
here as well on a Pantech PX-500; the suggestion in comment #2 worked fine. 

Running rawhide if/when there are new packages to test.

Comment 9 Dan Williams 2009-02-13 15:18:03 UTC 
The patches that switched Pantech cards to the option driver were actually wrong and have been reverted upstream.  They will get into Fedora in the next stable kernel updates.  Upstream kernels with this issue fixed are 2.6.27.16 and 2.6.28.5.
