Hi Joao and everybody:

I hacked ubsa as well before posting in this list with no positive
result. My system do not detect any serial port. I'm very frustrated
with this issue because I can't use the modem in FreeBSD... an Option
HSDPA pcmcia doesn't work too... very very disappointed...  

Thanks, greetings,
