I recently bought a 3G mobile broadband modem and then realised I'd bought the wrong model - instead of getting a Huawei E160 or E169 that reportedly work OOTB with Intrepid I got a ZTE MF627 for which no information exists. On the plus side, it has a built-in MicroSD reader...
--EDIT
This should all now be taken care of by udev-extras. The modem will initially be detected as the ZeroCD device; after ejecting it from the desktop (or the Places sidebar in Nautilus) it will be re-detected as a modem.
$ sudo aptitude install udev-extras

I initially raised a bug here but in the meantime have got it working. So here is a how-to.
1) Download and install usb_modeswitch
Go here and download the deb file. A direct link to version 0.9.5 is here. Then install it.
This provides a way of switching the USB modem from its initial useless mode to its correct, functional modes. It will need configuring to apply to the modem.
2) Edit /etc/usb_modeswitch.conf to apply to the MF628+
Either comment the first modem configuration out, then find and uncomment the section for the MF628+, or (more easily) replace the content of the file with:
Save it.Code:######################################################## # ZTE MF628+ (tested version from Telia / Sweden) # # Contributor: Joakim Wennergren # # Also applies to MF627 (Tested 3 UK) JF DefaultVendor= 0x19d2 DefaultProduct= 0x2000 TargetVendor= 0x19d2 TargetProduct= 0x0031 MessageEndpoint=0x01 MessageContent="55534243123456782000000080000c85010101180101010101000000000000"
3) Create a udev rule to automatically run usb_modeswitch when the modem is plugged in
Create a new file called 999-zte-rules:
gksudo gedit /etc/udev/rules.d/999-zte.rules
Its content should be as follows:
This will trigger usb_modeswitch every time you plug in the modem. Which is useful if you want it to work automatically.Code:SUBSYSTEM=="usb", SYSFS{idProduct}=="2000", SYSFS{idVendor}=="19d2", RUN+="/usr/sbin/usb_modeswitch"
4) Add device information to HAL so network-manager recognises the device as a modem
Finally, in order for Network Manager to recognise the modem information has to be added to HAL.
Create a new file:
gksudo gedit /usr/share/hal/fdi/information/20thirdparty/20-zte-mf627.fdi
Its content should be as follows:
Save it.Code:<!-- -*- SGML -*- --> <deviceinfo version="0.2"> <device> <!-- ZTE MF627 HSDPA USB dongle --> <match key="@info.parent:usb.vendor_id" int="0x19d2"> <match key="@info.parent:usb.product_id" int="0x0031"> <match key="@info.parent:usb.interface.number" int="3"> <append key="modem.command_sets" type="strlist">GSM-07.07</append> <append key="modem.command_sets" type="strlist">GSM-07.05</append> <append key="info.capabilities" type="strlist">modem</append> </match> </match> </match> </device> </deviceinfo>
5) Plug in the modem
Make sure the SIM card is in the modem (and if you're using 3 UK make sure you're in a 3G area. otherwise it won't work) and plug it into your PC.
After several seconds the LED should light red as it powers up, then switch to blue when it finds a network. You can check it's working by checking dmesg: you should see entries for GSM modem, USB drive and CD drive. Once modeswitch has been triggered and the modem reboots you will be presented with the ZeroCD device (e.g. containing the 3connect software), a USB MicroSD card reader, and if everything has gone correctly, Network Manager will detect a new mobile broadband modem.
Feel free to ignore the ZeroCD device and unmount it from the desktop.
If everything has gone well dmesg should read something like:
