Hi there. I'm newby here, so sorry if I'm writing in the wrong place. However, this is the most similar thread to what I need that I've been able to find in the net.

I have a Novatel Merlin UX870 pc card (idxvendor=1410x1430) that I use as a modem. My OS is Xubuntu 9.04. My network-manager version is 0.7.1. My present linux kernel is version 2.6.28-17.

So far, everything worked ok. When I plugged in my card, it got detected by the system, properly loaded the modules (usbserial and option) and created the device nodes /dev/ttyUSB0 and /dev/ttyUSB1 (first one is the good one, the other I don't know its use), properly detected by NM, properly been able to create new mobile broadband connections with the applett netrowk-manager-gnome and, in general, all was happiness and joy.

But suddenly, since some days ago, after I-don't-know-what-I-may-have-possibly-done, NM doesn't like my modem any more. The system still sees it, and I can, for example, manually configure and "pon myconnection", and get online without problems. But NM refuses to accept the card.
The only relevant thing I remember having done recently is replacing the 2.6.28-15 kernel with the 2.6.28-17, but I'm not sure if that's the problem, as I think that dates of replacement/issue don't match. Besides, I've tried with another one kernel (2.6.24-23) and problem remains. So, probably that has nothing to do. I've a badly broken memory (in my head, I mean, not in the computer), but I don't remember having installed or uninstalled anything relevant. So, I'm at a loss.

Any clue? I'd very much appreciate some guideline or hint.

Useful information for somebody out there who will like to help me:

When plugged the card, or when restarted, NetworkManager logs that
(ttyUSB0): found serial port (udev: hal:GSM)
(ttyUSB0): ignoring due to lack of probed mobile broadband capabilities
(ttyUSB1): ignoring due to lack of mobile broadband capabilities

End of "nm-modem-probe /dev/ttyUSB0" command says that
modem_probe_caps(): GCAP response: +GCAP: +CGSM, +DS
ID_NM_MODEM_GSM=1
ID_NM_MODDM_PROBED=1
main(): /dev/ttyUSB0: caps (0x9) GSM

I've been modifying the /lib/udev/rules.d/77-nm-probemodem-capabilities.rules as suggested above in this post, tried all possible combinations, but NM insists in denying broadband capabilities to my card. Seems like if it wasn't running nm-modem-probe, or something...
