I’m on Mavericks (10.9.5) and fighting with a USB device with a “FT232R” chip (from FTDI) for USB to serial conversion.
Premium USB 20 to RS232 Serial DB9 10 Ft Adapter Cable Supports Windows 10 8 7 Vista XP 2000 98 Linux and Mac Built with FTDI Chipset and Hex Jack Nuts Model #: Ablxz-B076269TD8 Item #: 9SIAP81C051881.

- UGREEN USB 2.0 to RS232 DB9 Serial Cable Male A Converter Adapter with FTDI Chipset for Windows 10, 8.1, 8, 7, Vista, XP, 2000, Linux and Mac OS X 10.6 and Above. USB to RS232 DB9 Serial Male Converter Adapter Cable is designed to connect serial devices such as DB9 equipped PCs, routers, GPS, barcode scanners, label writers, serial modems.
- The USB to DB9 provides a connection between an available USB port and the more traditional RS-232 serial port found on many devices. This adapter is designed for connections to cellular phones, PDAs, digital cameras, modems, or ISDN terminal adapters through your USB port. Simply plug your device into the adapter and the adapter into your PC.
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.
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)
