wizard will open. It will discover and install the
USB device. Then it will discover and install each
serial port. Allow Windows to install the converter
"Automatically." There is no need to connect to the
Internet or Windows Update.
If a popup window says the software has not passed
Windows logo testing, that's OK. Just click on
"Continue Anyway."
