After rebooting the system, you can now plug the PL-2303 USB-to-Serial adaptor or cable to the USB port. You can first run the System Profiler program under the Applications-Utilities folder. Click USB hardware inside System Profiler and look for “USB-Serial Controller” or “USB-Serial Controller D”. This means that the hardware device is detected by your Mac computer.

cd /dev

ls tty.usbserial*

You should see the “tty.usbserial” device which means the USB serial device is already setup properly. If you try to plug another PL-2303 device, you should also see several “tty.usbserialx” listed where “x” is the assigned device number similar to Windows COM port assignment.

 

 NOTE: Mac OS may also pop-up a new network interface when it detects a new USB-Serial Controller device. See next section for more explanation.
