Do you @rvanderwerf have lines similar in your dmesg to
[ +0,74] bluetooth hci0: Direct firmware load for brcm/BCM-0a5c-6410.hcd
failed with error -2
[ +0,07] Bluetooth: hci0: BCM: Patch brcm/BCM-0a5c-6410.hcd not found
After copying the file BCM-0a5c-6410.hcd to /lib/firmware/brcm
I have tried copying the attached file but no change for me :(. I am
using 4.0.7-rc4 kernel as well :( My BT doesn't work at all.

Have you tried to put the file BCM-0a5c-6410.hcd in /lib/firmware/brcm
(on upstream kernel)?

A little more information:
- Current and upstream kernel see some bluetooth devices (probably cell phones
nearby), just not the keyboard and trackpad. These show up as general devices,
not input devices.
- Keyboard and track pad do not show up as any device type (they work on
windows on same
Since it is a new laptop, I do not know if it ever worked. But, there
were updates during the first week of use, so it is up to date.
I have tested upstream kernels before, but since this is my everyday
work laptop, and because it has an encrypted partition, I need to review
the changes I made
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.7-rc1
