This bug affects me too, and I have the right firmware installed. After
resume, but not every time, the firmware fails to load. See for instance
this output from dmesg | grep -i blue:

A workaround is to do 
sudo modprobe -r btusb
sudo modprobe btusb

Title:
  firmware: fw-04ca_2007.hcd will not be loaded

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Upon wakeup from standby, I see: "firmware: fw-04ca_2007.hcd will not
  be loaded", followed by "Bluetooth: can't load firmware, may not work
  correctly".

  Reading several bugreports, it seems that I need to get that firmware
  file from somewhere, but I do not know how. Thus I would expect that
  Ubuntu ships a packet with the mentioned firmware file and
  automatically installs it, when such hardware is detected. An
  alternative would be to display instructions on where to find the
  firmware file.

  The full excerpt from dmesg is:
