Question

我想通过C ++ more or less using this way中的USB连接我的Beaglebone Black。

为了做到这一点，我需要在BBB和笔记本电脑上找到端口。

我的BBB挂在与主机相同的网络上，也通过USB连接。我尝试使用lsusb和ifconfig（下面的结果）找到该端口。

知道如何找到设备吗？

操作系统：在两个系统上都是ubuntu

在主机上有文件：

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

在BBB上有文件：

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

Answer 1

我猜你要与之交谈的端口是/dev/ttyACM0。

我怀疑“1d6b：0104 Linux基础多功能复合小工具”是对应于Beaglebone的条目。

拔掉Beaglebone时，1d6b条目和ttyACM0会消失吗？你可以在将Beaglebone插入USB后立即运行dmesg并向我们展示与您的笔记本电脑识别Beaglebone相对应的线路，以及之后的所有内容吗？

在ubuntu下找到特定的USB端口
