btw this is a 'RESET' command sent to the adapter as the first thing when 
the device is marked up.

the meaning of the INIT_ flags is that they are set and then when the 
RESET command is completed, we issue other commands and clear those flags 
when they have completed. because the RESET did not complete, they are 
still pending but I guess will not be issued.

Do you have a reference for this?  We have nothing to handle any such 
firmware loading that I know of; there is sysutils/bcmfw to do that for 
Broadcom devices (but, they can operate as a Bluetooth device by default 
just better with newer firmware)
