When using virtual XP each time you hook the remote into the USB, be sure to go to the top/center of the virtual page, click the USB, click your device ( in my case my MX-950 shows up as unknown device). After clicking the device in the USB pulldown box you can download and upload into the remote. As soon as you click the device in USB pulldown if the remote is plugged in, it will start its connection jingle signaling it’s link.
