[  +0,000074] bluetooth hci0: Direct firmware load for brcm/BCM-0a5c-6410.hcd failed with error -2
[  +0,000007] Bluetooth: hci0: BCM: Patch brcm/BCM-0a5c-6410.hcd not found

After copying the file BCM-0a5c-6410.hcd to /lib/firmware/brcm you can
also reload the btusb to force load without rebooting:

sudo rmmod btusb && sudo modprobe btusb

Title:
  Direct firmware load fails for bluetooth

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hardware: XPS 15 9550, BCM43602 Bluetooth
  Release: 16.04
  Main Symptom: Mac Key Board and Mac Trackpad not discovered, but other devices are discovered
  Details:

  Firmware not loading + misc errors.

  Edited /etc/init/bluetooth.conf to add -d on exec.
  sudo udevadm control --log-prioriry debug

  I am assuming the firmware or other errors explain the failure.

  Further Testing: Boot laptop on Windows 10 partition, both devices are
  discovered and work.

  Note: Bios has some setting to enable Wireless Switch, disable this
  does not help.

  The following are from the logs:
