Just got my alpha bid vag com. Interestingly enough my winxp netbook (dell mini 10v) recognized it an installed it with the ftdi drivers automatically. I'm thinking it's because I have already installed some FTDI usb/serial drivers for my arduino stuff.
I'll try and log after dinner and update this thread.
EDIT: I ended up updating the ftdi driver from 2.0 to the 2.8.x from the link on the OP.
