I found it in the /sys tree using `find /sys -name hci0`. In /sys I saw it uses the serial port /dev/ttyAMA0 Then I used fuser on /dev/ttyAMA0 to find this process: /usr/bin/hciattach /dev/serial1 bcm43xx 3000000 flow - I'm guessing the /dev/ttyAMA0 serial protocol will give me way more information on how the driver is behaving. There's likely some way to log the raw traffic. Unsure how difficult processing it would be.
