[Bug 1593477] [NEW] Direct firmware load fails for bluetooth

 

Public bug reported:

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:

Title:
  Direct firmware load fails for bluetooth

Status in linux package in Ubuntu:
  New

Bug description:

  Main Symptom: Mac Key Board and Mac Trackpad not discovered, but other devices are discovered
  Details:

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

  Further Testing: Boot laptop on Windows 10 partition, both devices are

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