changing a USB blutooth dongle mac address

sorry if this has been here before, but i have been driving my self  
mad on google and trying things, i am working on a bluegiga access  
server box, i need to be able to make the box think my computer is one  
of the phones in its oui list for testing, there for i need to change  
the mac address of my usb dongle.

ive been messing around with various bits and bobs on my command line  
but not sure if everything i have been doing is totally wrong.

last month i was not a hardware programmer... please help

if this kind of procedure is not one that should be in the public  
domain then please direct mail me

and clues suggestions or advice greatly received

i have built bluez from source with --enable-all , not really sure  
what commands i want to use or how to directly access the stick
