为此，我需要在BeagleBone Black和笔记本电脑上找到端口

我的BeagleBone Black与主机挂在同一网络上，也通过USB连接。我尝试使用

lsusb

和

ifconfig

查找端口（结果如下）

如何找到该设备

操作系统：两个系统上都有Ubuntu

主机上有以下文件：

```
/dev/ttyS[0-31]
```
```
/dev/ttyprintk
```
```
/dev/ttyACM0
```
```
/dev/tty[0-63]
```
```
/dev/tty

BeagleBone Black上有以下文件：

```
/dev/ttyS[0-3]
```
```
/dev/ttyGS0
```
```
/dev/ttyO0
```
```
/dev/tty[0-63]

我猜您要与之对话的端口是

/dev/ttyACM0

我猜想“1D6B：0104 Linux基金会多功能复合小部件”是对应于Beigle骨的条目。

拔下BeagleBone时，1d6b入口和ttyACM0是否会消失？在将BeagleBone插入USB后，您能否立即运行

dmesg

，并向我们显示与您的笔记本电脑对应的识别BeagleBone的线路，以及之后的所有内容？

是的。谢谢你的回答最后一段是对这个问题的评论。
