Install laptop bluetooth in debian 9.1


I am trying to install the firmware of the bluetooth card of my laptop and and I'm having problems.

My bluetooth model is (from lsusb):

Code:
Bus 001 Device 002: ID 04ca:2006 Lite-On Technology Corp. Broadcom BCM43142A0 Bluetooth Device
My "dmesg|grep Blue" is:

Code:
[   12.137580] Bluetooth: Core ver 2.22
[   12.137615] Bluetooth: HCI device and connection manager initialized
[   12.137620] Bluetooth: HCI socket layer initialized
[   12.137624] Bluetooth: L2CAP socket layer initialized
[   12.137632] Bluetooth: SCO socket layer initialized
[   14.314089] Bluetooth: hci0 command 0x1001 tx timeout
[   16.716328] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[   16.716334] Bluetooth: BNEP filters: protocol multicast
[   16.716349] Bluetooth: BNEP socket layer initialized
[   22.509378] Bluetooth: hci0: BCM: Reading local version info failed (-110)
[  162.409913] Bluetooth: hci0 command 0x1001 tx timeout
[  170.541220] Bluetooth: hci0: BCM: Reading local version info failed (-110)
It's the type of cards that work inside my laptop's wifi card, and I see that the package "brcm80211" does not support my bluetooth model: https://wiki.debian.org/brcm80211

I have read that it is as simple as downloading the .hcd for my model from: https://github.com/winterheart/broadcom-bt-firmware

In my case it would be exactly this file: "BCM43142A0-04ca-2006.hcd"

I have downloaded it and placed it in /lib/firmware/brcm

But it still does not work, I've wasted hours trying to fix this and I can not get it to work.

Any ideas? Thank you very much.

Any firmware loading failure will be in dmesg, knowing the reason why firmware does not load will help to solve the problem.

The only thing I find in the dmesg related to bluetooth is what I have already posted in the post, maybe this is the cause of the problem:

Code:
[   22.509378] Bluetooth: hci0: BCM: Reading local version info failed (-110)
[  162.409913] Bluetooth: hci0 command 0x1001 tx timeout
[  170.541220] Bluetooth: hci0: BCM: Reading local version info failed (-110)
And when I try to see my bluetooth device from blueman-manager or bluedevil does not appear to me.

Search brings up some interesting articles. Arch Wiki hints this device works in Linux.

I have solved it, if someone else happens to you it is as simple as renaming "BCM43142A0-04ca-2006.hcd" to "BCM.hcd"
