Yota, it will help immensely if you filed a new report with the Ubuntu
repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux
Please feel free to subscribe me to it.

I've been affected by this exact bug for over a year and have not been able to
use bluetooth.
dmesg:
[3.353578] Bluetooth: Core ver 2.21

Lorn Potter, thank you for your comment. So your issue may be dealt with as
soon as possible, and so your hardware may be tracked by having necessary
debugging information automatically attached, could you please file a new
report with Ubuntu by executing the following in a terminal while
I updated yesterday and this bug effects me (lenovo x1 carbon 1st gen).
I have no bluetooth now.
dmesg:
[ 73.111498] usb 1-1.4: new full-speed USB device number 7 using ehci-pci

Hi Christopher,
I have a feeling that the bluetooth device can preserve state when
rebooting, unless I take out the battery for a moment. In particular, it
can lock up. I have a feeling that firmware problems can cause that.
As a crosscheck, I've confirmed that everything works on Windows.

Title:
Bluetooth: can't load firmware, may not work correctly
uellue, if it works in Windows, then it clearly would be a Ubuntu versus
a hardware fault. As well, if you have to play all these games of
pulling out a battery, rebooting, etc. to get it to work in Ubuntu, it
would appear to be some wonky timing issue.
Despite this, in order to further narrow
Dear Christopher,
thank you for your patience and help. If I need to install an old Ubuntu
version in another partition to (maybe) fix this bug, I found actually
an easier way to use Bluetooth on my laptop: I am switching to Windows 7
as the primary operating system and put Ubuntu or maybe

Hi Christopher,
the behavior is unchanged after the BIOS upgrade.

I did the BIOS upgrade with the Windows utility. Other than not having
any noticeable effect on Bluetooth, it worked.

uellue, could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream
Hi Christopher,
With kernel 3.19-rc1, Bluetooth still does not work. However, the
behavior changed. This is what dmesg shows after unloading and loading
btusb:
[ 1058.704086] usbcore: deregistering interface driver btusb
[ 1058.752148] usbcore: registered new interface driver btusb
[
uellue, just to advise, it is most difficult to analyze the results when
one changes more than what was requested (in this case both the kernel
version and firmware).
Hence, could you please test 3.19-rc1 (with the default firmware) and
then advise to the results?

Hi Christopher,
the behavior is the same with both versions of linux-firmware.

uellue, could you please advise the kernel version you were using when
this was not reproducible in Precise (ex. 3.2.x, 3.5.x, 3.8.x, 3.11.x,
or 3.13.x)?

work again?

Hi Christopher,
with the old kernel it works even less: It doesn't find the device
anymore and the btusb kernel module is somehow blocked so that I cannot
unload it. With the new kernel it finds the device, but no operation
works on it.

uellue, ok, so this indicates that this isn't a linux (Ubuntu) kernel
regression, but in some other package. Next, could you please return
back to the default kernel, install the firmware from Precise (1.79.18,
or whichever earlier version from that you know worked), and advise if
