OK, here's the situation: The FTDI USB drivers that come with 0022 don't work on WIN7 64 bit.
Make a new folder under 0022/drivers I did 0022/drivers/WIN7FTDI
Unzip the ZIP into that folder. Make sure the subfolders get unzipped OK
Plug in your Duemilanove or Mega with FTDI USB Interface chip.
Go to device manager
You should see "FTDI Serial port" with Yellow "Bad" indicator under "other devices".
Right click on that.
Click "browse for driver". Navigate to new driver folder. Click "go or whatever"
-- you should see "Installing Driver" for a minute..
YOU'RE NOT DONE! You may have an error popup about "Driver not installed correctly"
AGAIN right-click the Yellow mark, Browse, Go. AGAIN you should see "Installing Driver"
NOW you should no longer see the FTDI entry under "Other devices" in Device Manager...
BUT you should now see USB Serial Port under "PORTS".
Now run the IDE, compile and upload GOBP (Good Old Blink Program).. OK?? You're set.
PLEASE, PLEASE add this to the Troubleshooting Page!!!
