Ralink RT3290 Bluetooth fails authentication

By Simeon Atanasov

I am on Linux Mint 18.1(same as Ubuntu 16.04) with kernel version 4.4.0-59-generic an installed the Ralink RT3290 bluetooth driver from this guide: RT3290 Ralink driver in Ubuntu. I used BlueZ to pair my phone with my computer and it always fails, then i tried with bluetoothctl and gives me the following output:

simo1427@the-master-linuxmint ~ $ bluetoothctl
[NEW] Controller 9C:2A:70:6B:F1:E6 the-master-linuxmint [default]
[NEW] Device 00:22:37:15:74:F2 JBL Micro Wireless

[bluetooth]# power on

[bluetooth]# agent on

[bluetooth]# pair 84:8E:DF:60:E8:FC

The same error is output when i try to pair my speaker with my computer.
