Bluetooth adapter not found in Manjaro XFCE with Ralink corp. RT3290

I am using Manjaro OS with XFCE dual boot along with Windows. When I use Windows, Bluetooth on my laptop connects and transfers data successfully. However, when I try to connect from Manjaro, it says “No adapter found”!
I have also noticed that the “Adapter” and “Devices” tab are greyed in Bluetooth Manager.

My laptop has Ralink corp. RT3290 Bluetooth built into it. On entering $bluetoothctl, I wrote the command

[bluetooth]# power on

It gave the output “No default controller available”.
