Native dependencies

Install native dependency: libusb 1.x.

The actual command to install depends on your OS and/or your distribution, see below

Debian/Ubuntu Linux

apt-get install libusb-1.0

On Linux, you also need to create a udev configuration file to allow user-space processes to access to the FTDI devices. There are many ways to configure udev, here is a typical setup:

# /etc/udev/rules.d/11-ftdi.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="0403", ATTR{idProduct}=="6001", GROUP="plugdev", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0403", ATTR{idProduct}=="6011", GROUP="plugdev", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0403", ATTR{idProduct}=="6010", GROUP="plugdev", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0403", ATTR{idProduct}=="6014", GROUP="plugdev", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="0403", ATTR{idProduct}=="6015", GROUP="plugdev", MODE="0666"

You need to unplug / plug back the FTDI device once this file has been created so that udev loads the rules for the matching device.

With this setup, be sure to add users that want to run PyFtdi to the plugdev group, e.g.

sudo adduser $USER plugdev

Remember that you need to log out / log in to get the above command effective.

Homebrew macOS

brew install libusb


Windows is not officially supported (i.e. not tested) but some users have reported successful installations. Windows requires a specific libusb backend installation.

Here is a brief setup guide from Andrea Concil for use with the libusb-0.1 backend:


  • install Libusb-win32-devel-filter from Libusb win32
  • before using it, install the so called “filter” so that libusb can coexist with specific peripherals usb drivers:
    • go into the Libusb-Win32 menu (it should be something like C:\ProgramData\Microsoft\Windows\Start Menu\Programs\LibUSB-Win32) and into the folder Class Filter launch the installation of the filter for all the usb devices i.e. Install all class filters. Once done libusb can be used “in parallel” with original drivers.


Another libusb backend implementation can be installed with Zadig
