Comments: How to Install FTDI Drivers


Comments 7 comments

  • On OSX El Capitan the FTDI driver wasn’t loading automatically for me even after unloading the built-in Apple driver. For those with similar problems you can manually load it from the terminal with

    > sudo kextload /Library/Extensions/FTDIUSBSerialDriver.kext

    Plug-in your device and then check that it worked. You should see something like

    > ls /dev/*usb* 
    /dev/cu.usbserial-XXXXXXXX  /dev/tty.usbserial-XXXXXXXX
  • There are more in depth tutorials on uninstalling and reinstalling drivers from FTDI if you really need => .

  • If you are on a Mac and not able to see the FTDI in your Arduino IDE’s listed COM ports, you need to install the FTDI drivers for your computer. When opening the iOS’s device manager located in the /Applications/Utilities under the USB tree, the computer was able to see the FTDI. Since the drivers were not installed, the FTDI did not enumerate properly. Try following the tutorial for installing a Mac =>

  • If you are using a school computer, you would need to install as an administrator in order to install the FTDI drivers on the computer. There was one case where a customer couldn’t get their FTDI cable working with the school’s Windows 10 OS. The administrator was finally able to get the FTDI working by installing as an administrator on the computer.

  • For users of OS X 10.9+ (Mavericks and later) a detailed description of FTDI driver options can be found here.

  • Yosemite isn’t 10.8, it’s 10.10. That said, on 10.10 these instructions don’t work, and reference an older version of these drivers. My Mac won’t connect to my Redboard no matter what set of instructions I use. Should have bought an UNO.

    • For Yosemite you only need to install drivers for D2XX operations. See

      Haven’t used a Redboard myself, there could be a problem if Sparkfun have changed the FTDI chip ID’s. Are you able to see the board in the OS X System Report? It should be under Hardware/USB somewhere. What values are reported for Vendor ID and Product ID?
