```
$ tail -n 2 /usr/lib/udev/rules.d/69-mixxx-usb-uaccess.rules
# Only some distribuions require the below
KERNEL=="hiddev*", NAME="usb/%k", GROUP="uaccess"

> If you did not install Mixxx from the Ubuntu PPA or RPMFusion, you may need to save save this file to /etc/udev/rules.d/mixxx-usb-uaccess.rules. You will need root privileges (use sudo or su) to copy the file to that location. Then, restart your computer.

Steps to reproduce:
1. system boot
2. `journalctl -b -p 3`
