After the latest update, bluetooth is working without a problem. No
workaround is required. However, bluetooth breaks after suspend resume.
Following is a hcidump of a suspend resume action.

Title:
  bluetooth devices no longer connect to the system

Status in “bluez” package in Ubuntu:
  Confirmed

Bug description:
  Up until some recent trusty update (maybe a week or two ago),
  bluetooth worked fine, but after the update none of my bluetooth
  devices connect to the system, nor can I add new ones. The devices I
  use are an LG HBS-700 headset, an Apple Keyboard and Trackpad. I
  plugged in an Asus atheros based bluetooth dongle to see if it was the
  Broadcom driver no longer working, but I have been unable to get that
  to work either and it has also worked successfully in Ubuntu before. I
  ran the bluez-hcidump command that was suggested, but it complains
  about no device being found.
