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 lsusb @ host：

答案 0 :(得分：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？
