Unity: Reading /dev/usb/hiddev

I am trying to read data from a Custom USB Device.

After researching, found out that Linux's hiddev items are not serial.

Is there anyway I get read /dev/usb/hiddev0 data in Unity for linux?

 using System.IO.Ports;

 void Start()
 {
       stream = new SerialPort("/dev/usb/hiddev0", 9600);//
       stream.WriteTimeout = 300;
       stream.ReadTimeout = 5000;
       stream.DtrEnable = true;
       stream.RtsEnable = true;
       stream.Open();
 }
