[Bug 1054307] Re: ATH3012 bluetooth not working


The problem still seems to be there even with the latest 3.12 kernel.
I am using a Scientific Linux 6 system, which originally uses a 2.6.32 kernel that does not provide the ath3k.ko module "out-of-the-box".
My experience is the following: When I power-on my system with the latest 3.12 kernel, the firmware of my Atheros AR3011 Bluetooth adapter (stored in the file /lib/firmware/ath3k-1.fw) obviously gets loaded properly with the kernel module ath3k.ko, since the "lsusb" command issued after system boot lists this adapter without any "complaints" about any missing firwware, which - in contrast to this - is the case when I boot kernel 2.6.32 directly after powering on my system.
However, even though the firmware seems to be loaded with kernel 3.12, the system is not able to use this bluetooth adapter. If I then just perform a system restart without any power interrupt in between (which obviously keeps the firmware inside of the adapter's RAM) and boot kernel 2.6.32 (which does not have the ath3k.ko, but "only" the btusb.ko module), my Atheros bluetooth adapter can be used by the system and I can successfully communicate with my various cell phones via the bluetooth interface....

Bug description:
  The problem is related to btusb and ath3k modules.

  I've prepared a patch that corrects the bug for kernel
  3.2.0-30-generic, but I suppose it can be easily extended to any
  kernel version.

  Other chips (with different VID:PID) may suffer the same problem.
