When directly after power-up, the System is first booted with MS Windows that already loads the firmware into the bluetooth adapter with the installed driver package and afterwards a "soft reboot" is made with the SL 6.4 OS, the bluetooth device is not working and the kernel also reports kernel: Bluetooth: Can't change to loading configuration err kernel: ath3k: probe of 1-1.5:1.0 failed with error -110 ALTHOUGH the ath3k-1-fw file is installed, which changes the product ID of the device after being loaded. Since the product ID is not changed by the firmware download performed by the Windows system, this observation means to me that the kernel and corresponding drivers always "think" that they have to download the firmware whenever a product ID value of 0x3002 is determined. If - as in this case - the firmware is already loaded any consecutive download attempts fail resulting in the above-mentioned error message... So obviously, the solution provided by the Ubuntu / Debian people who just adapted the firmware file to get the device working with the currently available kernel versions does not properly work either under all circumstances, i.e. a bug fix in the kernel drivers seems to be mandatory in my opinion. The kernel needs to be able to distinguish between a device which has its firmware already loaded and another which has it not yet by other means than just via the different product IDs... Warm embraces from 2019, where Bluetooth doesn't work yet.. I ran into problems with my matured PC which has Qualcomm Atheros AR9285 Wireless Network Adapter on-board (ASUS P9X79 DELUXE motherboard). I have different IDs though: $ lspci: 08:00.0 Network controller [0280]: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01) Subsystem: AzureWave AW-NB037H 802.11bgn Wireless Half-size Mini PCIe Card [AR9002WB-1NGCD] [1a3b:2c37] Kernel driver in use: ath9k Kernel modules: ath9k $ lsusb: Bus 002 Device 004: ID 13d3:3304 IMC Networks Asus Integrated Bluetooth module [AR3011] So it is originally = [1a3b:2c37] However, those who report the same device working say it should change IDs to [0cf3:3005] upon ath3k module loading (see: https://ubuntuforums.org/showthread.php?t=2409703&p=13828829#post13828829) My PC is dual-boot with Windows so probably I can play a little bit more with warm/cold restart and probably it will fix my problem. As for the firmware, here on Ubuntu 18.04 it has md5sum value of 24cfee59a24f336dfae838a0de6445a0 Ok, I've just checked. It doesn't depend on whether I boot Linux after Windows or not, it cannot load firmware at all. I blacklisted ath3k to load it manually, so when I issue: modprobe ath3k there goes 5-6 seconds delay and "Bluetooth: Can't change to loading configuration err" error in dmesg: [ 41.776857] NET: Registered protocol family 31 [ 41.776857] Bluetooth: HCI device and connection manager initialized [ 41.776860] Bluetooth: HCI socket layer initialized [ 41.776861] Bluetooth: L2CAP socket layer initialized [ 41.776865] Bluetooth: SCO socket layer initialized [ 46.833889] Bluetooth: Can't change to loading configuration err [ 46.833926] ath3k: probe of 2-1.5:1.0 failed with error -110 [ 46.834023] usbcore: registered new interface driver ath3k Kernel version: 4.15.0-13 Should I report it as a new bug? |
