    Broadcom BCM2035 Bluetooth problem.

    I'm having trouble with my Xubuntu 12.04 install recognising the bluetooth hardware in my Acer Aspire 2000 laptop (circa 2003).

    This laptop has a button that allows the bluetooth radio to be turned on and off. The symptom I am observing when I press this button is that the bluetooth icon appears briefly in the system tray then disappears. It does this each time I turn the radio on.

    Here's some machine logs to aid with diagnosis:

    As you can see everytime I press the button to turn on the bluetooth radio the driver appears to timeout and fail.

    I read in another forum that I may need proprietry firmware for this hardware so I installed:

    Code:
    sudo apt-get install linux-firmware-nonfree
    However this hasn't helped.

    Any suggestions would be appreciated.
