After upgrading to the kernel (from my PCMCIA aircard (Verizon PC5750) no longer works.  Network Manager reports "Unable to connect" message (see attached log dump from /var/log/messages ).  Attempt to use gnome-ppp fails as well.
Booting into the kernel (on same machine) and both Network Manager & gnome-ppp are able to connect correctly

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

How reproducible:
100% time in

Steps to Reproduce:
1.Plug in PCMCIA card
2.Network manager automatically tries to connect & fails
3. Open Terminal - su gnome-ppp
4. attempting to run Setup -> Detect hangs gnome-ppp
5. ctrl-c required in terminal to end gnome-ppp
Actual results:
PCMCIA CDMA card unusable/fails to connect

Expected results:
successful connection

Still does not work (same symptoms/errors) after updating kernel to

Only official fedora repo's are used for yum updating. No third party repos are used.

Modified bug summary to be non-version specific.

Can you post the logs from a working kernel?

ttyUSB0 will not work; the connection needs to be made using ttyUSB1
Comment 6 David Hollis 2009-02-02 11:10:14 EST
How do we tell this to NetworkManager?
Comment 7 Brianna 2009-02-02 13:34:42 EST
I was able to successfully connect using gnome-ppp but only if I manually entered /dev/ttyUSB1 in setup (attempting to use detect still fails & hangs the system).  

Network Manager is still unhappy (but I have to find the correct config info to modify).

Since it appears the naming conventions have changed in the kernel does this need to be listed as a bug in gnome-ppp & Network Manager?

I don't know why NM doesn't know to use /dev/ttyUSB1... I'll copy the maintainer.

Upstream patch that caused the problem is reverted in

Updated to Kernel this past weekend and aircard now works as expected (both with gnome-ppp and NM)
