I am working on an Android product and I'm porting some test code from using the Android hal layer to using just Linux. I have the bcmbtusb driver and BlueZ built, but I can't see any USB controllers in hcitool or the Bluetooth daemon.
I saw that in Android there is some hal code which contains functions to initialize the Bluetooth device (a BCM20704), including uploading the firmware, and I can see it being called during the Android boot.
I'm looking for some help in doing the same thing but under raw Linux rather than Android.
