Info about Karmic modem manager and mode switching?
Hello all, we know there is many 3G modems not yet properly recognized and/or connected by modem/network managers in 9.10. I have been searching around for information how the whole new modem-manager thing goes, but I have not been able to find much. Could someone tell if there is info somewhere about modem-manager plugins, different modem-modeswitch options etc? I am not a SW developer, but would like to try some tailoring for certain problematic modem models.

Re: Info about Karmic modem manager and mode switching?
Hello Antti, I had the same problem, on my case NetworkManager was selecting a random device from the 4 devices recognized from my Vodafone 3G PCMCIA Card. I was directed to the following wiki page: https://wiki.ubuntu.com/DebuggingModemmanager Fortunately on my case the problem is already fixed on the daily trunk, anyway I would like to understand how it works to isolate the fix and backport to the stable version. I was investigation my problem based on HAL information (lshal, 10-modem.fdi) from looking into similar bug reports, after looking at the modemmanager source I have found I was looking at the wrong place since udev is now used replacing HAL. From mm-manager.c I have found that mm scans/handles devices with subsystem tty and net . You can get a list of the currently detected udev devices with: udevadm info --export-db Now. I need to find where is the modem date retrieved from I guess there is an equivalent to hal-info with the modem information. Hope it helps.

Re: Info about Karmic modem manager and mode switching?
Thanks Joao, this is a good start. I have already made an own udev rule file for selected modems requiring eject or usb_modeswitch and with it I already get the modems nicely to modem mode. Even though, that is not enough because network manager: a) does not recognize these modems at all or b) sees the modem but connecting to the net miserably fails. In addition, if the modem-modeswitch could do the same as usb_modeswitch I would like to learn to use that instead, as it is readily there in Ubuntu. Seems that there is only one type option-zerocd available. Is it possible to add different types (like in usb_modeswitch) here?
