How do I make ubuntu recognize the bluetooth adapter in my computer, I have Ubuntu 12.10.
This is a well known bug with Linux and the Bluetooth adapter used in Acer computers, which is HonHai/Foxconn. Please have a look at this bug report:
As far as I know, it is said that a fix was released some time ago. However, my personal experience is that it still doesn't work on Acer computers. So I don't think you can make your Bluetooth work until a proper bug fix is released, or until you fix this bug, if you're able to :) If you do, please let the rest of us know.
