So just got my first board, a Nano V3. Already had Arduino 1.0 installed, Vista auto installed the FTDI USB converter device/driver upon USB-NanoV3 connection.
Windows device manager indicates that it has been successfully installed & assigned com port 2 - if I remember correctly "port_#0002.hub_#0005". Nano powers up and is apparently pre-loaded with 'blink'.
The only ports that show in Arduino are the bluetooth ports. When I disable the bluetooth device no com ports appear, even after repeated re-boots & re-connects.
In case of firewall conflicts I tried disabling Norton 360 & Teatimer (SpybotSD) to no effect.
Please help.... New at this. Cheers
