Electronic charting without a serial port...
A friend of mine sent his computer to me with the same complaint. I had to reome windows XP and install windows 2000 Pro in order for the USB to serial port to work correctly. Once that was done and the Capn Voyager was installed it found the GPS data on Comm port 5. Works great now, in fact we are using the second USB port with another serial adapter and interfacing to a pactor modem which is also working fine on Comm port 7.
