As I said I do not have you device and cannot check. I thought you were looking for an adapter, not a mouse, but if you are looking at the properties option half way down the right click menu for the adapter, that is all I can suggest.
If you look at the printers, that is what I would expect your device would show. An option to change com ports. Have you installed all the drivers for the adapter?
If you are using it for a mouse, they make adapters that just plug into the mouse to convert it. I may be looking at it wrong. Two devices may be listed on one hub.
