Public bug reported:
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:
