Description Davide Repetto 2013-09-03 12:06:15 UTC
Description of problem:
=======================
the device affected is a "BT-USB-M1" from Dynamode:
Bus 005 Device 015: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

It is working properly with kernels at least up to 3.9.5-301.fc19 but with current 3.10.10-200.fc19 and 3.10.10-100.fc18 it is not working anymore.
Please note that I didn't test with kernels in between since they're not in the repos anymore.

The same kind of problem has surfaced in the past and was described here:
https://bbs.archlinux.org/viewtopic.php?id=126603&p=2

A kernel bug was already opened and resolved here:
https://bugzilla.kernel.org/show_bug.cgi?id=42932


Version-Release number of selected component (if applicable):
=============================================================
kernel 3.10.10-100.fc18 both i686 and x86_64

How reproducible:
=================
Always

Comment 1 Josh Boyer 2013-09-18 20:32:20 UTC
*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs.

Fedora 19 has now been rebased to 3.11.1-200.fc19.  Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.

Comment 2 Davide Repetto 2013-09-20 02:08:04 UTC
Unfortunately the problem still persists with kernel 3.11.1-200.fc19 both on 32 and 64bit hardware. Same exact output in the logs.

Comment 3 Dan Leong 2013-09-23 21:09:12 UTC
Also a problem on Fedora 18 Kernel 3.10 onwards. 3.9.11 is fine.

Existing bug at kernel.org, with (not accepted) patch :-
https://bugzilla.kernel.org/show_bug.cgi?id=60824

Comment 4 Paul Steckler 2013-12-24 22:28:14 UTC
I have a Microsoft-branded bluetooth dongle, actually made by Broadcom, that exhibits similar behavior under FC20, kernel is 3.11.10-301.fc20.x86_64. I get 
the message

  Can't init device hci0: Operation not supported (95)

when running "hciconfig hci0 up".

I kept around an old FC19 kernel, 3.9.8-300.fc19.x86_64. The same command succeeds when running that kernel.

Comment 5 Fedora End Of Life 2015-01-09 19:42:20 UTC
This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 19 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 6 Davide Repetto 2015-01-10 16:09:39 UTC
Still happens in Fedora 21 with kernel kernel-3.17.7-300.fc21.x86_64 and Bluetooth: Core ver 2.19

Comment 7 Raphael Groner 2015-02-24 08:30:05 UTC
There was another user who reported this issue with Fedora 20 and 21.

Comment 8 Fedora End Of Life 2015-11-04 13:28:41 UTC
This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '21'.

Comment 9 Davide Repetto 2015-11-04 16:26:06 UTC
Problem is still there for me in F23 - current kernel.

Comment 10 Davide Repetto 2016-07-27 16:45:34 UTC
Closing.
It works again in kernel 4.6.4-300

Comment 11 Rodd Clarkson 2020-05-11 23:20:27 UTC
This is broken again in FC32 (and FC31)
