Linux - 与设备关联的端口(Linux - port associated to a device)

 我有一个开发板通过USB连接到我的Linux机器。 为了调试我想监视串口。 我的问题是我不知道应该如何理解我应该监视哪个串口。  
 在终端中运行lsusb时，我明白了  
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0461:4e1d Primax Electronics, Ltd 
Bus 001 Device 004: ID 0d28:0204 NXP LPC1768
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 046d:c019 Logitech, Inc. Optical Tilt Wheel Mouse
Bus 003 Device 002: ID 03f0:c511 Hewlett-Packard 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
 
 我感兴趣的设备是NXP LPC1768，因此它“连接”到设备04的Bus01。但是，我应该监控哪个端口来读取该NXP LPC1768设备的串行端口？  
 运行dmesg | grep tty 我明白了  
[    0.000000] console [tty0] enabled
[   97.204143] cdc_acm 1-1.2:1.1: ttyACM0: USB ACM device
 
 但这仍然没有给我那些我正在寻找的信息。  
 当我使用Windows时，我会转到设备管理器，端口选项卡，查看与设备关联的COM端口，并使用Putty等软件监控串口。  
 你怎么能在Linux中做到这一点？  
 我很抱歉，如果之前已经问过这个问题，但我已经搜索了一个小时但仍然找不到答案.. 

I have one development board attached via USB to my Linux machine. For the sake of debugging I want to monitor the serial port. My problem is that I don't know how understand which serial port should I monitor.  
When running lsusb in the terminal, I see 
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0461:4e1d Primax Electronics, Ltd 
Bus 001 Device 004: ID 0d28:0204 NXP LPC1768
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 046d:c019 Logitech, Inc. Optical Tilt Wheel Mouse
Bus 003 Device 002: ID 03f0:c511 Hewlett-Packard 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
 
The device I am interested in is the NXP LPC1768,so it is "attached" to Bus01, device 04. However, which port should I monitor to read the serial port of that NXP LPC1768 device? 
When running dmesg | grep tty, I see 
[    0.000000] console [tty0] enabled
[   97.204143] cdc_acm 1-1.2:1.1: ttyACM0: USB ACM device
 
but this still doesn't give me that information I am looking for. 
When I used Windows, I would go to the Device manager, Ports tab, see the COM port associated to the device and use software like Putty for monitoring the serial port.  
Do you how can I do that in Linux? 
I'm sorry if this question has been asked before but I've searched for an hour and still couldn't find the answer..

 从代码中删除了大量的margin和padding 。  
 增加position: relative; ， text-align: center; ， width: 100%; 到#nav 。  
 另外，增加margin:0; 和padding:0; 到*  
 注意：由于某种原因，你没有img in li 。  
 改为：  
*{
    margin:0;
    padding:0;
}
#nav {
    position: relative;
    top: 0;
    height: 3em;
    line-height: 3em;
    text-align: center;
    width: 100%;
}
#nav ul {
    margin: 0;
}
#nav ul li {
    display: inline-block;
    font-size: 0.9em;
}
#nav ul li a {
    display: block;
    color: inherit;
    text-decoration: none;
    height: 3em;
    line-height: 3em;
    padding: 0 0.5em 0 0.5em;
    outline: 0;
}
 
 用于悬停下划线。  
 尝试这个：  
#nav ul li a:hover {
    border-bottom: 3px solid #eee;
}

Removed a lot of margin and padding from your code. 
Added position: relative;, text-align: center;, width: 100%; to #nav. 
Also, Added margin:0; and padding:0; to * 
Note: You didn't have img in li for some reason. 
Change to this: 
*{
    margin:0;
    padding:0;
}
#nav {
    position: relative;
    top: 0;
    height: 3em;
    line-height: 3em;
    text-align: center;
    width: 100%;
}
#nav ul {
    margin: 0;
}
#nav ul li {
    display: inline-block;
    font-size: 0.9em;
}
#nav ul li a {
    display: block;
    color: inherit;
    text-decoration: none;
    height: 3em;
    line-height: 3em;
    padding: 0 0.5em 0 0.5em;
    outline: 0;
}
 
For underline on hover. 
Try this: 
#nav ul li a:hover {
    border-bottom: 3px solid #eee;
}
