[FIXED] Can you get a list of connected devices in java

Issue

Im new to java and am just wondering if you can receive a list of connected USB devices, for example:

If i created a java program to modify devices, i want the JFrame to display a list of devices for the user to select one... (That's not my idea, or my intention but that is the best example i can think of, sorry.)

Solution

Using the javax.usb library, we can get information about the UsbHostManager.

import java.util.*;
import javax.usb.*;

public class USBLister {

  public static void main(String[] args) throws UsbException {
    //Get UsbHub
    UsbServices services = UsbHostManager.getUsbServices();
    UsbHub root = services.getRootUsbHub();

    listPeripherique(root);
  }

 public static void listPeripherique(UsbHub hub) {
    //List all the USBs attached
    List perepheriques = hub.getAttachedUsbDevices();
    Iterator iterator = perepheriques.iterator();

    while (iterator.hasNext()) {

      UsbDevice perepherique = (UsbDevice) iterator.next();
      System.out.println(perepherique);

      if (perepherique.isUsbHub())
        listPeripherique((UsbHub) perepherique);

    }
  }
}
