i think i've found fix it, based on information bug registered meego at: https://bugs.meego.com/show_bug.cgi?id=3498
solution execute following command (needs executed sudo):
bccmd psset -s 0x0000 0x028c 0x0001
doing allows bt adapter see other devices turning on radio, appears bt device active, radio not. setting appears stay in device long remains powered on. in order avoid having manually input command every time power on machine, embedded command within init.d script bluetooth daemon, @ /etc/init.d/bluetooth. i'm running ubuntu 11.04 64-bit, , here's script looks (the modification right below comment containing "ralink"):
#! /bin/sh
