使用usb4java，在JAVA中获取设备的UBS信息

usb4java官网示例 (opens new window)

导入依赖

<dependency>
    <groupId>org.usb4java</groupId>
    <artifactId>usb4java-javax</artifactId>
    <version>1.3.0</version>
</dependency>

配置

在资源目录下生成文件javax.usb.properties 并写入下面内容

javax.usb.services = org.usb4java.javax.Services

简单示例

@Slf4j
public class UsbUtil {

    /**
     * 查找指定 PID VID 设备
     * @param vendorId VID
     * @param productId PID
     * @return 是否USB设备
     */
    public static boolean findDevice(short vendorId, short productId) {
        try {
            UsbHub rootUsbHub = UsbHostManager.getUsbServices()
                    .getRootUsbHub();
            UsbDevice device = findDevice(rootUsbHub, vendorId, productId);
            return null != device;
        } catch (UsbException e) {
            log.error("USB检测异常",e);
            return false;
        }

    }
    /**
     * 在一个Hub中查找指定 PID VID 设备
     * @param vendorId VID
     * @param productId PID
     * @return 是否USB设备
     */
    @SuppressWarnings("unchecked")
    public static UsbDevice findDevice(UsbHub hub, short vendorId, short productId) {
        for (UsbDevice device : (List<UsbDevice>) hub.getAttachedUsbDevices()) {
            UsbDeviceDescriptor desc = device.getUsbDeviceDescriptor();
            if (desc.idVendor() == vendorId && desc.idProduct() == productId) return device;
            if (device.isUsbHub()) {
                device = findDevice((UsbHub) device, vendorId, productId);
                if (device != null) return device;
            }
        }
        return null;
    }


}
