5DT Glove- COM port not opening

Hello,

I have a 5DT glove that I wish to use with Unity. I have the wrapper included in my file, and my functions are working fine. However, my glove won't open. It's an old model (5 sensor serial) and I have it plugged in through a Serial-to-USB connector. In the Glove Manager program provided by 5DT, the glove connects and reads inputs on COM3. Here's my code:

using UnityEngine; using System.Collections; using FDTGloveUltraCSharpWrapper; using System.Runtime.InteropServices;

public class glovedriver : MonoBehaviour {

 CfdGlove fdGlove;
 
 // Use this for initialization
 void Start () {
     
     fdGlove = new CfdGlove();
     fdGlove.Open("COM3");
 
 }
 
 // Update is called once per frame
 void Update () {
     
     if(fdGlove.IsOpen ()){
         
         print ("Working");
     }
 
     else{
         print ("Not Working");
     }
     
 }

}

Is the glove too old to work? Should I try opening on USB instead? Any help is appreciated.
