CID: 201307-13942 Dell Latitude E5540
The Bluetooth can't find any devices after switch the Wifi slider from OFF to ON
Error message could be found in dmesg:
[ 98.149145] Bluetooth: can't load firmware, may not work correctly
Steps:
1. Install 14.04.1 + update (3.13.0-37) + proprietary Broadcom driver
2. Make sure BT is working, turn the Wifi slide to disable it
3. Turn it on again, try to pair with a Bluetooth mouse.
Expected result:
* Bluetooth works well after re-enabled.
Actual result:
* Nothing can be detected.
