Bluetooth not detected by default with ath9k driver

Bug Description

Bluetooth exists in the hardware, but is not detected by Ubuntu. Bluetooth coexistence is off by default (ie there is no modprobe ath9k btcoex_enable=1 wherever that needs to live).

Either this should be on by default (and we sort the problems), or we need an easier way to switch it on with the ath9k driver.

If all thats needed is a module option to enable it you can simply add that to /etc/modprobe.d/ath9k.conf, add 'options btcoex_enable=1'.

Yes I know that. The question is why isn't it on by default - thus
irritating the average user who doesn't want to delve around in conf
files.

Still not working by default in lucid.

I have an HP mini 110-3016tu. I am having the same problem.

 bluetoothd[1108]: Failed to find Bluetooth netlink family

this is in syslog.1

Bluetooth seems to start initializing but I cannot seem to use my bluetooth...

System -> Preferences -> Bluetooth says that there are no Bluetooth adapters found. I believe it is a coexistence with my atheros 9285

I'm new to this so is there anyone who can give me some pointers.

The module option was removed from lucid and turned on by default if the hardware supports it. Can you test whether or not this works in natty and provide the hardware id (from 'lspci -vv')?

Having dug around in the guts of this machine, it looks like the bluetooth bit is 'optional' for this particular submodel - so the hardware actually isn't there.

Which explains a few things...

Marking invalid.

lordskid, please file a new bug report for your bluetooth issue, as it looks to be unrelated to the original report.
