COM problems Windows XP

I have my cord plugged into the computer but it won’t recognize it. When I go to device manager it is not there. When I go to devices and printers it is there but it does not have a location when I right-click on it.

Easel? Or COM port in general? What machine? Controller?
If Easel,

I built the machine and I think it is the computer because it works on my other laptop.
