Ubuntu 16.04 can't find bluetooth devices

Question

Recently got a new laptop and successfully installed Ubuntu on it. However, unlike my other debian laptops, this one seems unable to discover my bluetooth headset.

I tried using bluetoothctl:

power on
agent on
default-agent
scan on

no error messages, but no results came out.

Then I tried hcitool:

hcitool scan

but still came blank.

Blueman also wasn't of much help. The bluetooth interfaces weren't blocked either, according to rfkill

I noticed that this appeared in my dmesg:

bluetooth hci0: Direct firmware load for brcm/BCM.hcd failed with error -2

Finally, the output of sudo service bluetooth status is

● bluetooth.service - Bluetooth service
   Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
   Active: active (running) since Sat 2017-01-07 15:57:22 GMT; 41min ago

Output of lsusb:

Any suggestions on what to try now?

Your BT device is 0930:0225. I added support of this device to the kernel. http://kernel.ubuntu.com/git/ubuntu/ubuntu-xenial.git/commit/drivers/bluetooth/btusb.c?id=36877fcdcb200d3163b11f82d594bd7dfec5ec36 — Pilot6, Jan 07 '17 at 16:46
@Pilot6 I don't seem to be having any dmesg errors or anything now, but when I try putting the power on via bluetoothctl, it says No default controller available -_- — towc, Jan 07 '17 at 17:18
Are you sure you converted the correct file? Not the one that is in the other answer? — Pilot6, Jan 07 '17 at 17:19
@Pilot6 for me that would be BCM43142A0_001.001.011.0197.0217.hex, right? I then turned it into BCM43142A0-0930-0225.hcd using hex2hcd, and when I noticed that the output of cat /proc/version was Linux version 4.4.0-57-generic (buildd@lgw01-54) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4) ) #78-Ubuntu SMP Fri Dec 9 23:50:32 UTC 2016 I renamed it to BCM.hcd, and finally copied that into /lib/firmware/brcm — towc, Jan 07 '17 at 17:23
It looks correct. The BT should work. What about rfkill list? — Pilot6, Jan 07 '17 at 17:26
@Pilot6 nothing blocked:
0: Toshiba Bluetooth: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no 2: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: no 3: hci0: Bluetooth Soft blocked: no Hard blocked: no — towc, Jan 07 '17 at 17:26
@Pilot6 just re-powered off and on again. Controller issue is fixed for some reason. Thanks. Should I delete the question? — towc, Jan 07 '17 at 17:37
Keep the question. It will point other people the right direction. — Pilot6, Jan 07 '17 at 17:41
