BCM2045 Bluetooth USB Device detected but not working

[Robert Woods]

Previous version of Ubuntu worked with my USB Bluetooth dongle (I used it for Bluetooh mouse). However 140.4 LTS onwards is detecting the device, but the device cannot be enabled in any Bluetooth manager.

Linux Asus-N56V-Ubuntu 3.16.0-45-generic #60~14.04.1-Ubuntu SMP Fri Jul 24 21:16:23 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Have noted that this issue is common to several varieties of Bluetooth adapter, but raising this because this specific adapter did work in previous versions of ubuntu (64bit 12.10)

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1482914

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.2 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'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Have run apport and allowed launchpad to do it's thing, bit confused as to what it was doing, didn't look like it was successful. Anyway, moving on to do the kernel update to see if that fixes anything.

[Robert Woods (imailuk)]

Just updated Kernel to latest (unstable) - 4.3.0-040300rc4-generic

So, as a noob, I'm a little confused - adapter works fine when booting to the various windows dual boot options I have on the same machine, but not Ubuntu (although prior to my upgrade to 14.04 on the same machine it did work).

Will run up Apport again post Kernel update.....

Ooops, cant post APport after Kernel update, requires posting into upstream Kernel something or other! So, what is here will have to do - suffice to say that using the upstream kernel (latest) has exactly the same 'bug' - again, think if this was resolved would be great for a very large number of Broadcom BT users:
