java实现监听USB(监听器无法生效，估计还是需要通过jna实现)

import javax.usb.*;
import javax.usb.event.UsbServicesEvent;
import javax.usb.event.UsbServicesListener;


public static void main(String[] args) throws Exception {

		UsbServices services = UsbHostManager.getUsbServices();
		UsbHub root = services.getRootUsbHub();
		listDevices(root);
		services.addUsbServicesListener(new UsbServicesListener() {
			@Override
			public void usbDeviceAttached(UsbServicesEvent event) {
				try {
					UsbDevice device = event.getUsbDevice();
					// 获取设备信息
					String deviceName = device.getManufacturerString() + " " + device.getProductString();
					String deviceId = device.getUsbDeviceDescriptor().idVendor() + ":" + device.getUsbDeviceDescriptor().idProduct();
					// 打印设备信息
					System.out.println("USB device attached: " + deviceName + " (ID: " + deviceId + ")");
				} catch (UsbException e) {
					throw new RuntimeException(e);
				} catch (UnsupportedEncodingException e) {
					throw new RuntimeException(e);
				}
			}

			@Override
			public void usbDeviceDetached(UsbServicesEvent event) {
				try {
					UsbDevice device = event.getUsbDevice();
					// 获取设备信息
					String deviceName = device.getManufacturerString() + " " + device.getProductString();
					String deviceId = device.getUsbDeviceDescriptor().idVendor() + ":" + device.getUsbDeviceDescriptor().idProduct();
					// 打印设备信息
					System.out.println("USB device detached: " + deviceName + " (ID: " + deviceId + ")");
				} catch (UsbException e) {
					throw new RuntimeException(e);
				} catch (UnsupportedEncodingException e) {
					throw new RuntimeException(e);
				}

			}
		});
