again, the usb-modeswitch of 3.8.4 works perfectly in 4.0.2.
i did heavy testing and there is no doubt that it works with my hardware and my configuration.
but nevertheless your dmesg in your other thread showed me, that your recognized modem is switched to a mass storage device.
that's the first point you should solve, otherwise it can't work.
have a look at
http://sourceforge.net/projects/comgt/on the base of these configuration files i found my own way to connect.
this program is tiny and works almost on any distribution (i copied just the few files to the right places).
perhaps it gives you a good starting point.
