发送消息时usb4java错误: USB错误1:控制传输失败:输入/输出错误

Question

我尝试用usb4java api发送一条消息到ir读和写元素，其中包含以下代码：

public static void sendData(DeviceHandle handle, int timeout) {
    
    ByteBuffer buffer = ByteBuffer.allocateDirect(12);
    buffer.put(new byte[]{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12});
    buffer.rewind();
    
    
    int transfered = LibUsb.controlTransfer(handle,
            (byte) (LibUsb.REQUEST_TYPE_CLASS | LibUsb.RECIPIENT_INTERFACE),
            (byte) 0x09, (short) 2, (short) 1, buffer, timeout);
    if (transfered < 0) {
        throw new LibUsbException("Control transfer failed", transfered);
    }
    System.out.println(transfered + " bytes sent");
    
}

但是每次我试一次，我就会在int = controlTransfer(handle, (LibUsb.REQUEST_TYPE_CLASS | RECIPIENT_INTERFACE), 0x09, (short) 2, (short) 1, buffer, timeout);上得到这个错误

Exception in thread "main" org.usb4java.LibUsbException: USB error 1: Control transfer failed: Input/Output Error
    at usb.reader.USBReader.sendData(USBReader.java:56)
    at usb.reader.USBReader.main(USBReader.java:42)
Java Result: 1

也许你们中有人知道怎么解决这个问题？

我真的很期待你的回答。

编辑：我想我必须说我的操作系统是Windows8.1 64位上VM VirtualBox中的Linux64位。(USB转发被激活；我已经访问了USB设备)

    int transfered = LibUsb.controlTransfer(
            handle,
            (byte) (LibUsb.REQUEST_TYPE_CLASS | LibUsb.RECIPIENT_INTERFACE),
            (byte) 0x09, //bmRequestType
            (short) 256, //wValue 
            (short) 0, //wIndex
            buffer, TIMEOUT);

值wValue=256
