troubles with bluetooth configuration

[freeze]

 Hello
 When I try to initiate my local bt (/etc/rc.bluetooth start ubt0), I
 receive an error message: Can`t load ng_bluetooth.
 I`ve suuposed that is because ng_bluetooth.ko module not loaded, but I
 wrong. I`ve load ng_bluetooth.ko and some other BT modules (like
 ng_btsockets etc), but I`ve received new error: ngctl: can`t create a
 node. permission deny.

 P.S. In my /dev dir I don`t see any ubt devices, it is normally? Even
 when I attach my BT into the usb.
