Having difficulty getting my laptop running windows 10 to communicate with my new XFI 2.05. I have followed the user manual protocol without success. The xfi controller & powertrain harness have power. The error received is "comm failure". Have attempted to establish communications with the ignition on (which I expected but not stated in the start up protoco) and with the ignition off. I have selected comm ports 1 thru 4 without success receiving the same " comm failure". I have checked all connections & physically moved the harness to multiple usb ports. Could there be an issue like the absence of the communications driver software? Any help would be appreciated. Thanks
