I have a laptop with 2 BT adapters, one internal (Broadcom BCM2045B; WIFI+BT adapter) and one external (CSR USB BT Dongle). I want to use only the latter because it supports Bluetooth 4.0, unlike the first one. On Ubuntu 14.04, how can I disable the first one permanently and make the system use the latter (I guess by setting the it to hci0 and the internal to not hci0)? I'll appreciate the help.
