Bluetooth seems to work now on my computer. I made a mistake by installing btusb. I got the driver from a dropbox-folder somewhere in the internet, and additionally I had to install a dkms-package. It's a little bit strange for me that I coudn't find the btusb-driver linked on any Ubuntu-Distribution Site or in the Softwarecentre. You find only some different dkms-packeges, which I tried beforer, to get bluetooth working (without any result of course!). 
I think it would be helpful, to upload the btusb-driver on the http://packages.ubuntu.com/ Site! 
If it's already on it, please send me a link.

Thanks!

Bug description:
  Broadcom bluetooth chips require a tool called patchram uploader [1]
  to load firmware. This applies to at least BCM20702 and BCM43142.
  Although some of the devices have an OTPROM that contains required
  firmware, but it is found that these devices would not have HFP/HSP
  support unless a upgraded firmware is loaded via patchram uploader.

  This tool requires hci device to do the firmware loading, but this may
  cause some race condition between patchram tool and bluetoothd or
  something that also works on hci interface.

  Also it needs some hooks to make firmware loads after bootup, s3,  s4,
  rfkill, and device hotplug events. Implement this loader in kernel
  module would make things more easier.
