使用Java读取USB设备的最佳方法是什么?

Question

我想写一个与机械臂相连的应用程序，机械臂通过USB连接到我的电脑上。我想要使用Java .

到目前为止，我还没有找到一个可靠的方法来实现这个连接。

我能得到一些关于使用什么和如何使用的建议吗?

Answer 1

下面的代码在win32-x86-64上为我工作:

import org.usb4java.*;

public class SO72998852 {
public static void main(String[] args) {
int status = LibUsb.init(null);
try {
if (status != LibUsb.SUCCESS) {
throw new LibUsbException("Unable to initialize libusb.", status);
}
DeviceList list = new DeviceList();
try {
status = LibUsb.getDeviceList(null, list);
if (status < 0) {
throw new LibUsbException("Unable to get device list", status);
}
for (Device device : list) {
DeviceDescriptor descriptor = new DeviceDescriptor();
status = LibUsb.getDeviceDescriptor(device, descriptor);
if (status != LibUsb.SUCCESS) {
throw new LibUsbException("Unable to read device descriptor", status);
}
System.out.println(descriptor);
}
} finally {
LibUsb.freeDeviceList(list, true);
}
} finally {
LibUsb.exit(null);
}
}
}
