Hi

Ubuntu 14.10 / I follow instructions and got my BCM43142A0-0a5c-21d7.hcd
in /lib/firmware/brcm.

dmesg | grep Bluetooth

[   16.456618] Bluetooth: Core ver 2.19
[   16.456641] Bluetooth: HCI device and connection manager initialized
[   16.456648] Bluetooth: HCI socket layer initialized
[   16.456651] Bluetooth: L2CAP socket layer initialized
[   16.456661] Bluetooth: SCO socket layer initialized
[   16.460079] Bluetooth: RFCOMM TTY layer initialized
[   16.460090] Bluetooth: RFCOMM socket layer initialized
[   16.460094] Bluetooth: RFCOMM ver 1.11
[   16.566552] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[   16.566555] Bluetooth: BNEP filters: protocol multicast
[   16.566574] Bluetooth: BNEP socket layer initialized

So all looks perfect, but bluetooth is still not visible via interface
bluetooth menu. Did I miss something ?

Bluetooth is still disabled (Aspire E5-471G-53C8)

Title:
  Support for loading Broadcom bluetooth firmware

Bug description:
  Broadcom bluetooth chips require a tool called patchram uploader [1]
  to load firmware. This applies to at least BCM20702 and BCM43142.
  Although some of the devices have an OTPROM that contains required
  firmware, but it is found that these devices would not have HFP/HSP
  support unless a upgraded firmware is loaded via patchram uploader.

  This tool requires hci device to do the firmware loading, but this may
  cause some race condition between patchram tool and bluetoothd or
  something that also works on hci interface.

  Also it needs some hooks to make firmware loads after bootup, s3,  s4,
  rfkill, and device hotplug events. Implement this loader in kernel
  module would make things more easier.
