# tl;dr # Summary
Create a file like [`/etc/udev/rules.d/99-solo.rules`](https://github.com/solokeys/solo/blob/master/99-solo.rules), for instance the following rules should cover access in all cases: On Linux, by default USB dongles can't be accessed by users, for security reasons. To allow user access, so-called "udev rules" must be installed. (Under Fedora, your key may work without such a rule.)
Create a file like [`70-solokeys-access.rules`](https://github.com/solokeys/solo/blob/master/udev/70-solokeys-access.rules) in your `/etc/udev/rules.d` directory, for instance the following rule should cover normal access (it has to be on one line):
``` ```
# Solo bootloader + firmware SUBSYSTEM=="hidraw", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="a2ca", TAG+="uaccess", MODE="0660", GROUP="plugdev"
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="a2ca", TAG+="uaccess", GROUP="plugdev"
# ST DFU bootloader
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", TAG+="uaccess", GROUP="plugdev"
# U2F Zero
ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="8acf", TAG+="uaccess", GROUP="plugdev"
``` ```
Then run Additionally, run the following command after you create this file (it is not necessary to do this again in the future):
``` ```
sudo udevadm control --reload-rules && sudo udevadm trigger sudo udevadm control --reload-rules && sudo udevadm trigger
``` ```
A simple way to setup both the udev rule and the udevadm reload is:
```
git clone git@github.com:solokeys/solo.git
cd solo/udev
make setup
```
We are working on getting user access to Solo keys enabled automatically in common Linux distributions: <https://github.com/solokeys/solo/issues/144>.
# How do udev rules work and why are they needed # How do udev rules work and why are they needed
In Linux, `udev` (part of `systemd`, read `man 7 udev`) handles "hot-pluggable" devices, of which Solo and U2F Zero are examples. In particular, it creates nodes in the `/dev` filesystem (in Linux, everything is a file), which allow accessing the device.

This is for Linux systems only.
To install the official SoloKeys udev rules, allowing access to your key, run
```
make install
```
This should work assuming your system is reasonably up-to-date. If not, try
```
make install-legacy
```
