 Posted: Sat Mar 02, 2013 12:07 pm Post subject: [solved] AR9462 Bluetooth Kernel Support |
 |
|
I've installed Gentoo on my tablet and everything works except bluetooth. I've followed the bluetooth guide here and I can see the device but I can't actually use it. I am completely out of ideas. Things I have tried:
- I've upgrade my kernel to 3.8.1
- I have compiled every kernel module I could when building 3.8.1; That's almost 3000 kernel modules.
- I've installed the latest sys-kernel/linux-firmware-20130113
Here is a pastebin of the dmesg: dmesg

So, I've downgraded my kernel to 3.7.10 and I still can't scan for bluetooth periferals. While executing the following commands I do not get anything new in /var/log/messages:
| Code: | # hcitool dev
Devices:
hci0 20:68:9D:B8:69:D1 |
| Code: | # hcitool scan
Scanning ... |
| Code: | # hcitool info 38:E7:D8:44:C4:0D
Requesting information ...
Can't create connection: Input/output error |
The exact same setup (but on my older Dell E6400) does work. I read somewhere that sometimes windows will load some firmware into the bluetooth device and rebooting into Linux can get it to work but it'll stop working after a cold boot because the firmware gets dumped. Do I need to find a firmware for this hardware??

OK, so I've solved the problem. However somebody needs to update the kernel so it supports the AR9462 going forward. What I did to fix everything was modify two files in the kernel to add support for my bluetooth usb device: drivers/bluetooth/ath3k.c and drivers/bluetooth/btusb.c. In my case my bluetooth usb device ID (found from lsusb output) is 04ca:3008, so I searched those two files for 04ca and found what looked like a close match of 04ca and 3005. I duplicated that line in both files and changed the 3005 to my 3008. Then I recompiled my kernel (version 3.7.10) and everything worked!
| Code: | $ diff ath3k.c /usr/src/linux/drivers/bluetooth/ath3k.c
80d79
< { USB_DEVICE(0x04CA, 0x3008) },
108d106
< { USB_DEVICE(0x04ca, 0x3008), .driver_info = BTUSB_ATH3012 }, |
| Code: | $ diff btusb.c /usr/src/linux/drivers/bluetooth/btusb.c
138d137
< { USB_DEVICE(0x04ca, 0x3008), .driver_info = BTUSB_ATH3012 }, |
After those changes everything worked:
| Code: | # hcitool scan
Scanning ...
7C:2F:80:49:59:8E SL910
90:7F:61:70:D5:DC Acer Iconia W700 Bluetooth Keyboard |
I have paired my keyboard case and my cell phone. And just to confirm in case anybody is interested: The Acer Iconia w700 Windows 8 tablet works with Gentoo Linux! |

| This is just an update that Kernel 3.8.3 has this issue resolved. So there is no need to hack your kernel if you are using >3.8.3. |

@ dinominant
Hello,
I'am new to Gentoo Forum. I've seen that we have the same touchscreen/tablet.
I've a big issue with the right click on the touchscreen. Did you solve it? If yes, maybe you could help me with the configuration?
Thanks
