Bluetooth issue: no default controller available in bluetoothctl

Bluetooth isn't working for me. I have bluetooth on this machine:

My kernel version:

$ uname -a
Linux prime 4.14.5-1-ARCH #1 SMP PREEMPT Sun Dec 10 14:50:30 UTC 2017 x86_64 GNU/Linux

The bluetooth kernel module doesn't load at startup (which I'll tackle later) so I'm doing this:

$ sudo modprobe btusb
$ sudo systemctl restart bluetooth.service

The result:

$ sudo lsmod | grep -i btusb
btusb                  53248  0
btrtl                  16384  1 btusb
btbcm                  16384  1 btusb
btintel                16384  1 btusb
bluetooth             626688  4 btrtl,btintel,btbcm,btusb
usbcore               282624  8 usbhid,usb_storage,ehci_hcd,xhci_pci,btusb,uas,xhci_hcd,ehci_pci

$ sudo systemctl status bluetooth

From dmesg:

$ dmesg | grep -i blue

[  489.640912] Bluetooth: BNEP filters: protocol multicast

This is ultimately what I get:

$ sudo bluetoothctl
Agent registered
[bluetooth]# list
[bluetooth]# power on
No default controller available
[bluetooth]#

I think the controller is supposed to show up in rfkill as well, but doesn't (I can't say I know what rfkill does exactly):

$ sudo rfkill list
[sudo] password for shane: 
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

My expectation is that "list" in bluetoothctl would show a controller that I could select, but it doesn't show. Is this maybe a driver issue? Documentation seems to still be lagging because lots of solutions involve hciconfig, which doesn't appear to exist anymore. Any help would be appreciated.
