 |
|
Hello!
I just have bough the notebook. Wifi works well, but the linux kernel cannot determine the bluetooth device.
As I found the bluetooth device driver is ath3k. I recomplied the kernel, but nothing happened. But probably the firmware is'n loaded? From the help:
CONFIG_BT_ATH3K:
Bluetooth firmware download driver.
This driver loads the firmware into the Atheros Bluetooth chipset.
Say Y here to compile support for "Atheros firmware download driver" into the kernel or say M to compile it as module (ath3k).
Where that firmware should be found? How to instruct the kernel to load it?
I followed all instructions an http://www.gentoo.org/doc/en/bluetooth-guide.xml

I have found an partial solution: load toshiba_bluetooth module 
But, the BT system does not works properly anyway...
| Code: | # hciconfig -a
hci0: Type: BR/EDR Bus: USB
BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
DOWN
RX bytes:0 acl:0 sco:0 events:0 errors:0
TX bytes:66 acl:0 sco:0 commands:20 errors:0
|
When I do load blueman applet, it founds not any BT adapters... (before loading toshiba_bluetooth it simply exited).
The more interest thing is the infinite complain right after loading toshiba_bluetooth module and doing /etc/init.d/bluetooth restart:

That looks like an bug... I think I should do bug report somewhere? Can anybody point me that place?

hi DMoL,
at the moment I try to get tan Atheros bluetooth module to work again as well. It worked with linux 2.6.38, in 2.6.39.3 it suddenly stopped. It worked with the ath3k driver, but not to confuse you: It is a plain bluetooth chip in my case.
No success until now, so for now I answer some of your questions:
The firmware is usually stored in /lib/firmware
To get the binaries emerge sys-kernel/linux-firmware.
After that try loading the module as "modprobe ath9k btcoex_enable=1"
Please refer to http://linuxwireless.org/en/users/Drivers/ath9k/btcoex for more details. |

Hi skeimer
Thanks for you answer. I just have tried he .38 kernel, and there was no success. I have found, that the correct driver is toshiba_bluetooth, not ath3k.
After googling I decided to file the bug, because toshiba_bluetooth is exactly my driver (recently there was a need to apply a patch to toshiba_acpi). And it is not working
