ZTE MF668 not detected by network-manager

[Peter Silva]

Network manager initially totally ignores this modem.

initially presents, like so:
Bus 001 Device 004: ID 19d2:2000 ONDA Communication S.p.A. ZTE MF627/MF628/MF628+ HSDPA

Is similar to MF628, but destination usb mode int=0x0017, instead of 0x0015.
I did the usb-modeswitch, to get it go from 0x2000 -> 0x0017, but network-manager still did not see it.

/etc/usb_modeswitch.conf:

    DefaultVendor= 0x19d2
    DefaultProduct= 0x2000

    TargetVendor= 0x19d2
    TargetProduct=0x0017

    MessageContent="55534243123456782000000080000c85010101180101010101000000000000"

which hung, but eventually rebooted with the stick plugged in, and it was in 0x0017.

It creates /dev/ttyUSB0-3. /dev/ttyUSB1 responds to standard AT modem commands.
i modified the .fdi file for MF628

vi /usr/share/hal/fdi/information/10freedesktop/10-modem.fdi

/ZTE MF628
(to find that model) then add stanza under ZTE line like so:

    <!-- ZTE MF668 HSDPA USB dongle -->
    <match <email address hidden>:usb.product_id" int="0x0017">
    <match <email address hidden>:usb.interface.number" int="3">
    <append key="modem.command_sets" type="strlist">GSM-07.07
    <append key="modem.command_sets" type="strlist">GSM-07.05
    </match>

(straight copy of the ZTE MF628 entry... with 15 replaced by 17.)

I have a bare-metal install of lucid 10.04.2. The bug seems to have been resolved.

Rogers ZTE MF668 USB modem

Booted up with modem in USB socket. Later tried inserting the USB modem into a running system. Both worked. I document the "boot up" path here.

Wizard recognized and set up the modem as designed. That is, I right-clicked on the "network manager applet" icon in the right side of the upper panel, chose "enable mobile broadband", then proceeded to "regular click" the "network manager applet" icon and chose "new mobile broadband (GSM) connection". Rogers (Canada) presets were accepted unchanged.
