Raspberry Pi 2 with USB bluetooth

Hi everyone,
I installed Hass.io today on my raspberry pi 2. I have a bluetooth USB device that worked fine with hassbian but it seems to not work with Hass.io
Do I have to write a Addon for the device? Because I actually have no idea how to do so.
“hassio host hardware” does not show the device as well:

{
  "serial": [
    "/dev/ttyACM0"
  ],
  "input": [],
  "disk": [],
  "audio": {
    "0": {
      "name": "bcm2835 - bcm2835 ALSA",
      "type": "ALSA",
      "devices": {
        "0": "digital audio playback",
        "1": "digital audio playback"
      }
    }
  }
}

ACM0 is a Z-Wave usb stick that works fine.

Thanks in advance for any help.

Edit: inserted code block

okay so I found out that the bluetooth dongle uses a csr8510 chipset.
I guess I could make a copy of the raspberry pi 3 addon for the broadcom chipset and exchange the firmware binaries.
Could someone point out where to get the firmware files?
