CZ20/Linux

Are you trying to connect to your badge on a Linux system and is it not showing up in Chrome/Chromium? Here are two things you can try (adapted from Microbit instructions):

• If Chromium has been installed from the snap store, you have to run snap connect chromium:raw-usb to allow it to use USB.

• On some Linux distributions eg. Ubuntu, you may need to declare a udev rule. To do this:

1. Create a file at /etc/udev/rules.d/50-campzone2020.rules with the following content: SUBSYSTEM=="usb", ATTR{idVendor}=="cafe", ATTR{idProduct}=="4011", MODE="0664", GROUP="plugdev"
2. Add your user to the plugdev group (replace with your username): sudo adduser <your_username> plugdev
3. Restart the udev rules: sudo udevadm control --reload-rules
4. Open Chrome and try to connect again.
