I know this probably doesn't help but i was unable to get an alfa card recognized by my droid running bt5. Honestly I didn't put more than a days work into it but it looked like a dead-end project. The main difficulty is getting the phone to recognize the adapter and bring it up in a functional manner. I think it would take a better understanding of underlying android device management and then the ability of bt5 to properly read and recognize it once android has. If you make any progress please do post more. I'd be happy to work on this with someone!
