Using (K)Ubuntu 14.04 LTS on a HP Stream Mini desktop. It's in use as a HTPC and I'd like to get an aftermarket Bluetooth keyboard to work. I connect to a wired network so not bothered about the wifi although it does appear to be recognised and work.

$uname -a
Linux media 3.13.0-49-generic #83-Ubuntu SMP Fri Apr 10 20:11:33 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

It has a custom Broadcom BCM43142A0 wifi/Bluetooth card:

I Googled for the USB device ID which seems to be a HP custom part as the device ID isn't supported by other BCM Windows firmware/driver bundles. I found:


...which gives a link to http://wielki.tk/vostro/debs/bt-bcm43142-onereic_0.0+20111116somerville2_amd64.deb for the firmware (notice the USB device ID in that link is the same - 216D). I've tried (from that Mint link):

dpkg-deb -x bt-bcm43142-onereic_0.0+20111116somerville2_amd64.deb bt-bcm43142

sudo cp bt-bcm43142/lib/firmware/BCM43142A0_001.001.011.0028.0036.hcd /lib/firmware/fw-105b_e065.hcd

sudo rmmod btusb

sudo modprobe btusb

However dmesg still shows:

[ 1170.856683] usbcore: deregistering interface driver btusb
[ 1170.856766] Bluetooth: hci0 urb ffff88020f9de540 failed to resubmit (2)
[ 1177.432179] usbcore: registered new interface driver btusb
[ 1177.432184] usb 2-7: Direct firmware load failed with error -2
[ 1177.432189] usb 2-7: Falling back to user helper
[ 1177.444258] Bluetooth: can't load firmware, may not work correctly
[ 1179.449809] Bluetooth: hci0 command 0x1003 tx timeout

So I also tried copying that file to /lib/firmware/fw-0a5c_216d.fcd (i.e. renaming it according to the USB manufacturer/device IDs) and also /lib/firmware/brcm/BCM43142A0-0a5c-216d.hcd (as well as fw-0a5c_216d.fcd and fw-105b_e065.hcd in /lib/firmware/brcm). Still no joy with exactly the same problems in dmesg.

Presuming that this is the correct firmware, which I'm pretty sure it is, how can I get the btusb module to recognise that firmware file?

The Linux mint link suggests editing /etc/modprobe.d/bcm43142.conf but I don't have that file on my system?

ls /etc/modprobe.d/
alsa-base.conf          blacklist-firewire.conf     blacklistrare-network.conf  iwlwifi.conf
blacklist-ath_pci.conf  blacklist-framebuffer.conf  blacklist-watchdog.conf      mlx4.conf
blacklist-bcm43.conf    blacklist-modem.conf        dkms.conf                    vmwgfx-fbdev.conf
blacklist.conf          blacklist-oss.conf          fbdev-blacklist.conf

Many thanks for any help.


While the dropbox link in this post no longer works, this answer is left as-is for historical reasons.

It isn't the correct firmware

wget https://www.dropbox.com/s/olqnqevf698lddo/fw-0a5c_216d.hcd
sudo cp fw-0a5c_216d.hcd /lib/firmware/
sudo cp fw-0a5c_216d.hcd /lib/firmware/brcm/BCM43142A0-0a5c_216d.hcd
sudo modprobe -r btusb
sudo modprobe btusb

And it should work

  • And indeed it does. Thank you very much sir, you help is much appreciated. – d7029 Apr 30 '15 at 0:33
  • this is not an answer but rather an individual it support. The dropbox link does not work anymore. Without this file it is not helpful any more. – NilsB Nov 18 '18 at 9:20

    Most broadcom bluetooth questions since then have been marked as a duplicate of askubuntu.com/questions/632336/… that shows you how to make the firmwarefile – Jeremy31 Nov 18 '18 at 10:44
