Bluetooth - No default controller found

After installing Arch, I managed to connect my Bluetooth mouse to the system and all was good. Then for no apparent reason Bluetooth is no longer working. After restarting my system I check the Bluetooth service.

$ systemctl status bluetooth

bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)
     Active: inactive (dead)
       Docs: man:bluetoothd(8)

Jan 16 21:24:37 ceres systemd[1]: Condition check resulted in Bluetooth service being skipped.

To get it up and running I have been following the Bluetooth Wiki and enabling the btusb Kernel module which doesn't seem to be loaded.

$ sudo modprobe btusb
$ sudo systemctl start bluetooth
$ sudo systemctl enable bluetooth
$ systemctl status bluetooth

bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)

Now I try and configure bluez via the bluetoothctl CLI.

$ sudo bluetoothctl

Agent registered
[bluetooth]# devices
No default controller available

So following the debugging instructions I see the following.

$ sudo systemctl stop bluetooth
$ sudo /usr/lib/bluetooth/bluetoothd -n -d

While debugging I use the bluetoothctl CLI again I get the following additional output in the debug window.

bluetoothd[2928]: src/agent.c:add_default_agent() Default agent set to :1.116 /org/bluez/agent
bluetoothd[2928]: src/agent.c:agent_ref() 0x55bc704444b0: ref=1
bluetoothd[2928]: src/agent.c:register_agent() agent :1.116

But nothing more when issuing the "devices" command.

I am using bluez and bluez-utils. I did have blueman installed at one point but decided to remove that in order to troubleshoot bluez in isolation.

Are there some additional steps I can do to try to troubleshoot and resolve this issue? The odd thing is that it was working at one point.

Any help appreciated.
