Required Drivers

On most systems (such as Windows 10 or newer, or MacOS X), the Fomu board does not need any special drivers.

  • On GNU/Linux, you do not need to install any drivers, however, you may need sudo access unless you Setup udev rules to grant permission for using the USB device from a non-privileged account.

  • Windows systems earlier than Windows 10: you will need to install Zadig drivers.

Setup udev rules

Warning

This set up is for GNU/Linux only. Setting up these udev rules grants permissions for using the USB device from a non-privileged account.

On GNU/Linux, try running dfu-util -l. If you get an error message like the following, you should add a udev rule as to give your user permission to the USB device.

 dfu-util -l

Steps to set up udev rule

     sudo groupadd plugdev
     sudo usermod -a -G plugdev $USER
    

    Warning

    You must log out and then log in again for the addition to group plugdev to take affect.

  2. Use id $USER and/or groups to check you are in group plugdev:

     id $USER
     groups | grep plugdev
    
  3. Create a file named /etc/udev/rules.d/99-fomu.rules and add the following.

    SUBSYSTEM=="usb", ATTRS{idVendor}=="1209", ATTRS{idProduct}=="5bf0", MODE="0664", GROUP="plugdev"
    

    Note

    You need sudo privileges for creating this file.
