Description of problem:
I cannot use the ZTE MF626 usb modem with NetworkManager/ModemManager.
Tested with Fedora 10,11,rawhide.
The service is 3G from ZAPP/Romania.
Version-Release number of selected component (if applicable):
Tried with NetworkManager 7 (several versions), and NM/MM from Rawhide.
Steps to Reproduce:
1.plug ZTE MF626 usb modem
2.wait a little to settle down and eject the CD
3.new GSM modem is found by NM
4.select to connect from nm-applet, the led on the modem goes from orange to green but it does not connect (should be close thou)
some debug info from NM/MM is attached.

output from modemmanager with --debug option
as you can see, it goes pretty far with connection, but fails in the end.
One more thing, when I try to connect for the first time, it fails right away, when I try the second time, it does something, the led goes green, still does something, and then it fails after a while.

This is the output log of a working wvdial configuration with the same card.
(I modified the PIN string for security reasons)
The wvdial.conf is plain vanilla:
Init2 = ATZ E0 V1 X4 &C1 +CMEE=1;+CFUN=1;
Modem Type = Analog Modem
New PPPD = yes
ISDN = 0
Username = zapp
Init1 = AT+CPIN="6262"
Password = zapp
Modem = /dev/ttyUSB2
Baud = 9600
Phone = *99#
Its the same issue as the MF636 and other ZTE modems. Can you please provide the output of lsusb for the device as well.
*** This bug has been marked as a duplicate of bug 515412 ***
Here is the lsusb before usb_modeswitch:
Bus 002 Device 007: ID 19d2:2000 ONDA Communication S.p.A.
and after usb_modeswitch:
Bus 002 Device 008: ID 19d2:0031 ONDA Communication S.p.A.
However, I don't think my bug report is a duplicate of 515412, because my modem is recognized by ModemManager and NetworkManager as you can see from the attached logs.
I am able to create a new broadband connection with nm-applet and the process goes pretty far in talking with the modem.
Please see the text from the attachment_id = 363262 to see the detailed communication between modem-manager and the modem.
I can confirm this problem too, tested with F11 and latest updates, provider is Yesss from Austria.
I also don't think that this is a duplicate of 515412, because I can see the 'Create a new ....connection' option in the NetworkManager applet
Hm, strange, my girlfriend got it working on her notebook out of the box..
Sorry for the early report, I'll test it again next week.
