I’m on Mavericks (10.9.5) and fighting with a USB device with a “FT232R” chip (from FTDI) for USB to serial conversion.
It was not accessible in OS X (e.g. QuickTerm didn’t list it, only the Bluetooth Port + Modem).
Using an old Windows (in a Parallels VM on the same Mac) I could (and still can) access the device, switch it back and forth between OS X and Win, and send commands to it using a terminal SW.
- Ongoing macOS FTDI driver issues plague many users connecting the Arduino IDE to boards that use an FTDI chip. Since our boards use an FTDI chip for USB-to-serial communication, we have witnessed some of these issues when working with our boards using Mac and macOS.

This is signed by Apple and distributed by Parallax 8/2019.
In OS X it seems to be unknown, however, the USB Device Tree reports the FT232R USB UART correctly with Product ID and Vendor ID from FTDI.
But I want to get rid of the Win (VM) solution and installed the FTDI driver for Mac, didn’t work.
As suggested by FTDI for Mavericks
[ http://www.ftdichip.com/Support/Documents/AppNotes/AN_134_FTDI_Drivers_Installat ion_Guide_for_MAC_OSX.pdf ]
I have also disabled (renamed) the AppleUSBFTDI.kext, restarted and installed the FTDI driver (version 2.3, signed by Apple). The installer always tells me “success” but I still can’t see the driver /System/Library/Extensions/FTDIUSBSerialDriver.kext (should it be there?) and the device isn’t accessible from OS X.
I’ve tried again and again, there is no FTDI or USBSerial device listed in /dev when I plug it in or switch it back from Win - I guess because the (OS X) driver isn’t correctly installed?
Could someone help, please?
(I have little knowledge in OS X)

USB port types and names
USB (Universal Serial Bus) is an industry standard for connecting computers and other devices. It's available with many types of ports, and each type has a unique shape. On Mac computers, USB is available with these ports, depending on your Mac model:
USB-A
Type USB-A ports are commonly called USB, USB 2, or USB 3 ports, depending on the USB specification they support. They aren't reversible, so a USB-A connector plugs into the port only when oriented correctly.
USB-C
Type USB-C ports are available as either standard USB-C ports or Thunderbolt 3 ports that also support USB-C connections. They both look the same, and the connector plugs into the port in either orientation.
Learn more about identifying the ports on your Mac, as well as the adapters and cables you can use to connect older devices to type USB-C ports.
USB specifications
USB specifications are important primarily when you want the most speed and power for your USB device, or your device needs more power or is using too much power. Every USB port supports a particular USB specification, which determines the port's maximum>USB specifications on MacData transferPowerUSB 3.1 Gen 2
Also known as USB 3.2 Gen 2
Up to 10 GbpsUp to 15W at 5VUSB 3.1 Gen 1

To learn which specification is supported by a type USB-A or type USB-C port on your Mac model:
- Choose Apple menu > About This Mac, click Support, then click Specifications.
- Check the System Information app for more details, including about USB devices connected to USB ports on your Mac. Select USB in the sidebar, then select a USB bus on the right.

USB specifications all work with each other, but speed and power are limited by the cable or device that uses the earliest specification. For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it can't draw more power from the port than can be delivered over USB 2. In other words, to get the best performance, make sure that the USB port on your Mac and the USB cable to your device meet or exceed the USB specification of the device itself.

If your Mac doesn't recognize a USB device after you plug it into your Mac:
- Check all connections: Unplug the device from your Mac, then plug it back in, and make sure that all cables and adapters are securely connected at both ends. Test with another cable or adapter, if available.
- Plug the device directly into your Mac instead of a USB hub or other device, and if necessary test with a different USB port on your Mac or device.
- Some devices need their own software, such as drivers or firmware. Others work without additional software. Check with the maker of your device, and install all available Apple software updates as well.
- If your device came with an AC power adapter, use it. Some devices can be powered by the USB port on your Mac. Others need more power than your Mac can provide.
- Restart your Mac.
