I currently need to figure out what is the name of the port that my usb device is connected to. More specifically, I need to know what to put for the followingenter image description here

I am using a Mac, and I have run the command line system_profiler SPUSBDataType, and it gave me the following. The device of my interest is the second one: CP2102 USB to UART Bridge Controller. But how do I figure out what the serial port that this device is connected to? I need it for my first image.

Try running ls /dev/tty* in a Terminal before and after plugging your device into USB. If there is an entry that only appears when the USB device is plugged in, that would be the entry corresponding to the device.
