unfortunately, this is the "intended" behaviour. this device has the
ability to present itself as "mass storage" which will show up as a
cd-rom device where the windows drivers are stored on.

this is the way it works under windows:
- plug it in first time
- (auto)run the setup on the device for the win-driver
- as soon as the driver is loaded, the cd device disappears and a modem is 
detected

but when loading the ucom/ubsa stuff before umass, the device will
not be recognised as /dev/cdX and show up as a communication device
(ucom).

of course there must be a way for getting the serial device working,
because this is one of the most sold umts/hsdpa modems across eu and
many people run it under linux as well (there are no drivers from
the vendor provided except windows and mac).
i'm pretty sure there is some "message" or anything else which will
render this device switching to serial mode.
there is some code, which i found (doesn't compile/run under freebsd)
which "puts" this device in pure serial mode. maybe someone out there
is able to tell me, how/if this can be done on freebsd as well?
(btw, i'm not a c-guru)

do you (or anybody else reading this) have an idea, how to get this
device working and put it in serial mode "completely" ?

regards...

THIS IS THE C CODE WHICH WORKS (ANYHOW) ON LINUX:
