USB Host Shield Bluetooth dongle multiple controller

Projects Programming

Hi,
i'm a novice in USB Host Shield, i would like to know if it's possible to connect multiple devices with a Bluetooth dongle connected on a USB Host Shield.
I already have connected one Dualshock4 controller (PS4 pad) with Bluetooth (by pressing PS + Options buttons for 5 sec)

Shield used : https://www.amazon.fr/dp/B00GHD2ZIE
Library used : GitHub - felis/USB_Host_Shield_2.0: Revision 2.0 of USB Host Library for Arduino.
Arduino used : Arduino UNO

#include <PS4BT.h>

USB Usb;
BTD Btd(&Usb);

PS4BT PS4(&Btd, PAIR);

void setup() {
  Serial.begin(115200);
  if (Usb.Init() == -1) {
    Serial.print(F("\r\nOSC did not start"));
    while (1);
  }
  Serial.print(F("\r\nPS4 Bluetooth Library Started"));
}

void loop() {
  Usb.Task();

  if (PS4.connected()) {
    Serial.println("Well played !");
  }
}

But a second controller can't be connected the the bluetooth dongle.

I would like to know if there is a way to do this without adding hardware.

Thanks.
