# Adding udev rules on Linux

By default, Linux does not allow the use of unknown USB devices, so you need to add `udev` rules for your hubs. Pybricks provides a couple of ways to do this.

If you are using an Ubuntu-based Linux distro, you can install the `pbrick-rules` package from the Pybricks PPA. This method has the advantage of automatic updates.

{% include copy-code.html %}
```
sudo add-apt-repository --update ppa:pybricks/ppa
sudo apt install pbrick-rules
```

You can alternately install the rules using the `pybricksdev` command line tool:

{% include copy-code.html %}
```
pipx run pybricksdev udev | sudo tee /etc/udev/rules.d/99-pybricksdev.rules
```

If neither of these options is suitable, you can manually copy [this file](https://github.com/pybricks/pybricksdev/blob/master/pybricksdev/resources/99-pybricksdev.rules) to `/etc/udev/rules.d/99-pybricksdev.rules`.

After installing the `udev` rules, disconnect any affected devices and plug them back in. 

If this doesn't seem to work, try rebooting.

# Using Pybricks Code with Chromium

If you use Chromium as a snap package, you may get an error when you try
to install the firmware on a SPIKE hub or MINDSTORMS Robot Inventor hub via
USB. To resolve this, enable access to USB devices:

{% include copy-code.html %}
```
sudo snap connect chromium:raw-usb
```
