[Test Case] * open the unity-control-center, and select 'Bluetooth', try to turn on/off in top checkbox. I am on ThinkPad T61 with Ubuntu 13.10 installed. I disabled bluetooth on startup by adding: "echo disable > /proc/acpi/ibm/bluetooth" to /etc/rc.local. When I open gnome-control-center -> Bluetooth and click on the "ON/OFF" switch button, it switches on for a fraction of a second and then switches back to off. Below are dmesg lines corresponding to this event: [ 94.028110] usb 3-1: new full-speed USB device number 5 using uhci_hcd [ 94.194320] usb 3-1: New USB device found, idVendor=0a5c, idProduct=2110 [ 94.194325] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 94.194328] usb 3-1: Product: BCM2045B [ 94.194330] usb 3-1: Manufacturer: Broadcom Corp [ 94.388169] usb 3-1: USB disconnect, device number 5 The workaround is to type "turn connectivity on/off" combination of my keyboard (FN+F5) -- then both wireless and bluetooth go off, and when I type it again, bluetooth comes back ON.
