network manager fails connect via 3G usb stick

[Cesar Urquidez]

I have a 3G USB stick (E220 HSDPA from HUAWEI)
Ubuntu 8.10 and up to Jaunty alpha5 were able to establish network connection using this device.
However in Jaunty alpha6 and now in Beta versions, the device will work exactly only one time.
Upon plugging in the usb stick, a wizard will appear and inform that a 3g modem was detected.
It will then ask some questions such as region (tw for taiwan) and carrier (Chunghwa telecom).
The very first time a connection can be established.
But either unplugging and replugging device or rebooting, all connection tries fail.

In addition, two entries appear under the network icon menu with the name (Chungwa Telecom).
Looking at the daemon log, i noticed that in trying to select the first entry in the menu, the network manager tries to use /dev/ttyUSB0 as a modem dialup, this should be the correct one). The second entry causes the network manager to try to use /dev/ttyUSB1, which is not correct). Note both will fail to establish connection.
Note the very first time modem is detected and following through the wizard steps, only one entry appears.
After reboot or replugging, the second entry appears.
The image 3gmodemdouble.png is a screen shot of this double menu item entry.

I am attaching a compressed folder (3gStickNotFail) that contains
daemon.log ~ log of network manager
lshal.txt ~ output of lshal
dmesg.txt ~ output of dmesg

Another note to add.
When running under the Jaunty Beta live session, I was able to use the 3G usb stick, will little trouble.
Enclosed is the folder with logs for that session. in daemon.log it can be shown that the modem successfully makes connection.
