It does not seem easy to find a solution. Some people use Ubuntu Linux with kernel versions later than 2.6.32 and they complain that they are not able to use Bluetooth with the ath9k driver. My post #7 was just a suggestion for the case that your wireless chip was not properly identified, but I am unsure whether the option "btcoex_enable=1" has any effect on recent ath9k kernel modules.

Have you already successfully used Bluetooth with another operating system (e. g. Windows)? In this case it could be that your wireless adaptor is partly incompatible with the Linux driver. Sometimes there is a special switch or button or combination of function keys to be pressed in order to enable wireless or Bluetooth connectivity. Is there an option in the BIOS of your system to disable Bluetooth or WLAN?
