Finding connected USB port using the command line

Is there a command / utility that allows you to find which USB port is being used to currently connect to your Arduino ?

On a desktop computer ? Which operating system ? With a Python script ?
By the way, I don't know the answer. Try Google.

using cygwin on Windows, there's a /dev/ entry when the port is active. unplugging the cables identifies which

The Windows mode command lists all COM ports

Note that mode will show all COM ports and also CON (console)

What's wrong with the Windows Device Manager?

The basic answer is "no". You can find ports but you will not be able to identify what is what. E.g. you have two identical Arduinos connected.

@SteveMann, it will be difficult to use that for automation :wink:

The idea was to have a batch file in Windows to allow me to upload a sketch into several Arduinos, quickly.
It works but I have to manually edit the right COM port everytime.
