Problem with bluetooth adapter on Dell E6400

Hello guys. I have some problems using the bluetooth on a Dell latitude e6400. I've had a look in BIOS and it says its enabled, the only driver missing is "Broadcom USH" which I don't know what it is and the Dell Detect Utility doesn't find it. I don't know how to activate the bluetooth for use. The little LED near the WiFi is off. I will attach some photos.
