我有 BBB，我想遵循这一点”例子“。所以我执行 lsusb 并得到
Bus 001 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
我如何找出哪一个是“普通”USB，哪一个是 miniUSB？
我不想测试它，因为 miniUSB 已连接到电站。
提前致谢！

答案1
我确信有巧妙的方法可以从输出中解决这个问题，但通常我们只需看看连接到哪个端口的东西就行了。
例如，总线 001 似乎连接到 FTDI 设备，我猜想这是某种 USB 转串行适配器电缆。哪个物理端口连接到此电缆？
