For those who own a Netcomm NB1200 ADSL USB Modem and are looking for Vista drivers (unsupported by Netcomm) I found that any modem that has an Alcatel Dynamite USB Modem chipset will accept the Prolink Hurricane 8000 driver. You can download it from here:
http://www.prolink.com.sg/download/H8000_Vista.zip
I have also uploaded it onto driverguide

Thanks carlosk, can you post a driverguide.com link to this driver?
