USB bluetooth device not working.

Hi,
I am trying to get my new UB bluetooth adapter working on PC. I followed the instruction given in "https://wiki.archlinux.org/index.php/bl … lueZ_tools". When I use bluetoothctl, i don't see any controller. "No default controller available"

So I read through the forums and did the following as part of debugging.

lsusb output
========

lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 002: ID 046d:085c Logitech, Inc. C922 Pro Stream Webcam
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 001 Device 002: ID 046d:c07e Logitech, Inc. G402 Gaming Mouse
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

from the output, my understanding is "Bus 001 Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)" is my device.

i did plugged out the device plugged in. It seems to be detected again.

journalctl -f

RFKILL also shows nothing is blocked.

sudo rfkill list         
[sudo] password for chakra: 
2: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

after all this, i still can't get the default controller.

bluetoothctl
Agent registered
[bluetooth]# show
No default controller available
[bluetooth]# info
Missing device address argument
[bluetooth]# list
[bluetooth]# 

could this be because of the reason the mentioned in https://wiki.archlinux.org/index.php/bl … _available. I also have tried with the deprecated package, still no luck

Chakra
