I bought a Serial to USB Adapter. I also bought one of the NologyOBD II Auto Dynometer that has a serial end. My laptop only has USB Ports. I plug it in and it recognizes the Belkin Serial to USB Adapter but does not see the nology OBD reader or the automobile data. I tried manually changing to another Com Port but did not work. I'm just trying to figure out a way to make it work.
