Controllers
PS3 Dualshock Controller Bluetooth
When connecting my controller to my Linux Mint emulation machine, it would ask for a pin. This was strange as I never had to do this before, and it would worked wired just fine. Here is the work around
sudo nano /etc/bluetooth/input.conf
# find and change line
ClassicBondedOnly=false
# after saving file, restart service
sudo systemctl restart bluetooth
