I need to use a MacBook Pro (OS 10.10.5) USB port with a serial circuit board. I want to use the built-in USB serial port (System Information, USB Bus, USB2.0 Serial) but I cannot configure it or have serial communications with my device. How do I do it?
Mac Pro, Mac OS X (10.6.5)
You need to get a serial adopter that works with a Mac. Like:
Thanks for the reply.
I have a PLUGABLE USB Serial Connector similar to the one you recommend. I would prefer to use a USB "Printer" cable (which I have) Type A Male to Type B male. I'm trying to connect to a Arduino Mega 2560 circuit board that has a Type B FEMALE input.
I don't know how to access the serial port (built in) on my MacBook Pro--I've tried everything I cannot figure out how to access this port. Ultimately I think using Mac's built-in serial connection is the eventual solution.
I can't use the PLUGABLE USB Serial Connector because of it's 9-pin connector, hence the search for an adapter. However, PLUGABLE Product Support writes "Thank you for contacting us about our serial adapter. Unfortunately, there is no connector I know of that will allow you to operate a USB printer from our serial adapter. Even if the pins could be matched, the protocols and voltages are not compatible."
Help is always appreciated. Thanks.
Type B FEMALE input.
Type B female is a USB port, not a serial port. If both the port you are using and the device you are connecting to are USB devices, there is no longer ANY configuration needed or available. You just plug it in and it works.
The days of 1200 bits/sec, one and a half stop bits, odd parity, and DTE and DCE devices and crossover cables are long gone (and good riddance).
Well I'm going on 3 months with this hiccup. Here are my error messages. Certainly I'm not doing something right. Nothing's getting through.

It is telling a file does not exist:

User configuration file does not exist or ...
That is an invisible file, but it appears it needs to to be present for anything else to work.
How do I configure PowerBook Pro USB SERIAL port?
