我想使用 jmtp.jar 监视连接到我的 linux 操作系统的便携式设备。下面是我用来做同样事情的代码。它在 Windows 中运行良好，但是当我运行此代码时，它给了我“不支持的操作系统异常”。jmtp.jar 支持 linux 操作系统吗？如果没有，那么 Linux 操作系统的任何替代解决方案？

我使用的代码

import java.io.*;
import java.math.BigInteger;
import jmtp.PortableDevice;
import jmtp.PortableDeviceManager;
import jmtp.PortableDeviceObject;
import jmtp.PortableDeviceStorageObject;

public class Jmtp {

public static void main(String[] args) {
    PortableDeviceManager manager = new PortableDeviceManager();
    PortableDevice device = manager.getDevices()[0];
    device.open();

    System.out.println(device.getModel());

    System.out.println("---------------");

    // Iterate over deviceObjects
    for (PortableDeviceObject object : device.getRootObjects()) {
        // If the object is a storage object
        if (object instanceof PortableDeviceStorageObject) {
            PortableDeviceStorageObject storage = (PortableDeviceStorageObject) object;

            for (PortableDeviceObject o2 : storage.getChildObjects()) {
                System.out.println(o2.getOriginalFileName());
            }
         }
      }
    manager.getDevices()[0].close();
    }
 }

我得到的例外：

Exception in thread "main" java.lang.RuntimeException: not supported os
    at jmtp.PortableDeviceManager.<init>(PortableDeviceManager.java:37)
    at find_usb.Jmtp.main(Jmtp.java:24)
