Bluetooth Issue on ....

Hi, I'm a new fan of the Knoppix USB System and so far it works great. Right now the only trouble is that on my Laptop HP Pavilion g6-1b67ca I can't get Bluetooth to work with Knoppix 6.71

1) The Bluetooth device is identified as:
root@Microknoppix:/home/knoppix# lspci
7:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter
(PCI-Express) (rev 01)

2) Synaptic Package Manager shows the following packages as installed:
bluetooth, bluez, bluex-alsa, bluez-audio, bluez-cups, bluez-gstreamer,
bluez-utils and libbluetooth3.

3) I find the Bluetooth Icon under Preferences in the Main menu and when I click on it the
Bluetooth Preferences window opens. Here it says: "Bluetooth is disabled" and
click on "Turn On Bluetooth" button doesn't do anything.

What is missing and what can I do?

PS.: I added a line to /etc/apt/sources.list like this:
deb http://ftp.de.debian.org/debian squeeze main and refreshed the packages in Synaptic in order to get Bluetooth packages.

Unfortunately not working for my computer!
It is not a USB Bluetooth device but a built-in Atheros chip! See orig, post.

Any other idea?

I think that if there exists a kernel module corresponding to your bluetooth device then you could simulate unplugging and replugging of your bluetooth adaptor by using the program 'modprobe'. See the manual page of modprobe. The program 'lsmod' delivers you a list of the currently loaded kernel modules.

'lsmod' gives me Modules listed with Size and Used-by info.

mac80211 --- 154215 --- 1---ath9k
ath9k_common --- 1448--- 1--- ath9k
ath9k_hw --- 248527--- 2--- ath9k,ath9k_common
ath--- 10270--- 2--- ath9k,ath9k_hw
cfg80211 --- 98209--- 3--- ath9k,mac80211,ath

I guess that the entries with "ath" are the modules for Atheros but I'm not able
to find out if any of them support the Bluetooth device which is listed by 'lspci':

07:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

How can I find out what is needed?

Maybe it is possible to follow the instructions at the end of the page "ath9k bluetooth coexistence" of the Linux Wireless web site.

Should I try this although it says HERE ?

Enabling bluetooth coexistence
Bluetooth coexistence is automatically detected and enabled as of 2.6.32 so you do not have to do anything for it.

Knoppix 6.7.1 uses Kernel 3.0.4 and xorg 7.6 (core 1.11) for supporting current-most computer hardware.

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?

It works in Windows7 from where I connect to my Desktop Computer and my HP printer. I'm going to check the BIOS and let you know.

10 min later: Nothing in BIOS related to Bluetooth or WLAN. One Key at the keyboard allows dis/enable WLAN.

With 'lspci -v', the system detects the AR9285 Wireless Network Adapte correctly: root@Microknoppix:/home/knoppix# lspci -v

I googled a lot without success..Is there hope?

YES, there is hope....! Knoppix-USB is Awesome! Fast, Flexible, Rock Solid! How I got Bluetooth working: 1) ---> Menu ---> Preferences ---> Desktop Session Settings - --> check mark on Bluetooth Manager ---> OK 2) ---> Menu ---> Preferences ---> S.P.M. (Synaptic P...) ---> Reload Packages and afterwards mark the packages 'bluetooth', 'bluez' and related blue* packages for upgrade! 3) After that was finished, the Bluetooth Icon appeared at the menu bar and Bluetooth was ready to go! Now, the neat part is, after restart all the new settings and upgrades are store at the USB stick and available again! Connected to the Laptop are Desktop PC, Printer, Cellphone, (wireless mouse and WiFi)! Thanks Knoppix Team ...way to go!
