Could you try the following and see if bluetooth works?

sudo -i
modprobe btusb

Glaf (lxndr) wrote :

Thanks, Josse!

It's works!

Previously, this did not work. I have read in the Bug #854399 about patches and decided to try to compile linux kernel.

How to close this ticket?

Jesse Sung (wenchien) wrote :


If you turn power off, and turn it on again, then go through the commands as above, does bluetooth work?
If it works, then we can generate a patch for supporting it. :)


Glaf (lxndr) wrote :

No, after reboot bluetooth is not work.
Really, it is bug.

But i use sleep mode in my notebook. This bug is not critical for me.

This bug is awaiting verification that the kernel for Oneiric in -proposed (3.0.0-16.29) solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-oneiric' to 'verification-done-oneiric'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!

Could you give the -proposed kernel a try by following the instructions in comment #32?
If it's not verified before Friday this week, the fix will be dropped. :(

Everything seems to indicate that this has been merged into the kernel and it should be supported, yet Ubuntu indicates "No Bluetooth adapters found".

Is this actually fixed or not?
