列出连接我的设备的 USB 端口名称，Mac。

Question

我现在需要确定我的USB设备连接的端口名称，具体来说，我需要知道为以下内容填写什么：

我正在使用Mac电脑，运行了命令行system_profiler SPUSBDataType，得到了以下信息。 我需要的设备是第二个: CP2102 USB to UART Bridge Controller。但是我怎样才能确定这个设备连接的串行端口呢？我需要它填写我的第一个图片。

Answer 1

在插入设备到USB端口之前和之后，在终端中尝试运行ls /dev/tty*命令。如果有一项只在USB设备插入时出现的条目，那么这将是对应该设备的条目。

Answer 2

在 MacBook 上执行以下操作：

# device not plugged in
ls /dev/ > notPluggedIn.txt

# device plugged in
ls /dev/ > pluggedIn.txt

# find what you plugged in
diff notPluggedIn.txt pluggedIn.txt
