To manually configure your Wolfram product’s read/write access to Vernier devices, you need to create a file named wolfram-vernierlink-libusb.rules, place it in the correct udev rules directory and ensure that the file has suitable permissions.

This process requires sudo, and your system may require you to enter your system administrator credentials.

1. To create the configuration file and grant all users read/write access, execute in a terminal:

   echo "SUBSYSTEM=="usb", ATTRS{idVendor}=="08f7", MODE="0666" 
   SUBSYSTEM=="usb_device", ATTRS{idVendor}=="08f7", MODE="0666"" >> wolfram-vernierlink-libusb.rules

2. Copy the file to the udev directory.

   sudo cp wolfram-vernierlink-libusb.rules /etc/udev/rules.d

3. Make the file visible to all users.

   sudo chmod 0644 /etc/udev/rules.d/wolfram-vernierlink-libusb.rules

Updating permissions

Some Vernier devices may require unplugging and re-plugging before changes in their permissions are recognized.

If the permissions do not update automatically, evaluate:

sudo udevadm control —reload
sudo udevadm trigger

Reverting permissions

To remove access to Vernier devices, delete the file.

sudo rm /etc/udev/rules.d/wolfram-vernierlink-libusb.rules
