I am trying to install my Garmin device (garmin gps 18x usb) so that I can use it in ArcMap, but always I am having the following error.

Unable to detect GPS device on COM ports supported by the hardware. Make sure Your GPS is turned on, connected properly, and sending data. Also review the Baud rate, Stop bits, Data bits, Parity settings for the port on this dialog.

    Your GPS is a USB device. You probably need to do some port mapping on your machine to expose it as a COM port – Ben S Nadler Sep 24 '16 at 15:31
