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:
