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

[Dennis Schridde]

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:

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Version 3.16.1-031601.201408140014 of linux-image-3.16.1-031601-generic does not show the problem.

[Dennis Schridde (devurandom)]

The message appears (with the Ubuntu kernel) everytime the computer returns from standby.

[Pilot6 (hanipouspilot)]

You need to load firmware. It can't be distributed with Ubuntu due to legal reasons.

You can fix it yourself.

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
