    Firmware for 04ca:2007 can be extracted from the latest Lenovo E145
    Bluetooth driver for Windows (driver is however described as BCM20702
    but contains also firwmare for BCM43142).
    Search for BCM43142A0_001.001.011.0122.0153.hex within hex files, then
    it must be converted using hex2hcd utility. Rename file to
    BCM43142A0-04ca-2007.hcd, then move to /lib/firmware/brcm/.
