Bluetooth Problem

[zungul]

Hi,

I pair my Plantronics Calisto Pro Bluetooth Headset to my desktop computer (win7 x64), and it showed that everything is OK but when I tried to use, it doesn't work.
When I press icon of sound on the taskbar and I go to Playback or Recording there is there Bluetooth Hands-free Audio but is Disconnected, and I don't have any idea how to connect this and make to work.
Can someone help me to solve this problem? I will really appreciate any help.
P.S.
I did everything like supposed to be. I attached few images to show my situation.
Like you see everything looks OK, but when I try (1 pic)to press Control for Calisto, nothing will happen and (5 pic) when I try to press Connect for Bluetooth nothing happened too

Hi,
Yesterday I bought USB BT400 Adapter.
I started everything from beginning and there is exactly the same situation. Nothing changed. If you look to the picture, everything is pair and installed and when I ask them, they said that was something wrong with Windows configuration (not 100%).
Point is that they didn't have any clue what is wrong.

The Plantronics BT dongle is inserted and successfully seen by the OS.
The headset is successfully paired with the dongle.
Windows sound configuration successfully 'sees' the BT adapter.
P.S.
I didn't mention that before when I installed USB Bluetooth Adapter, and I pair my device in the Playback and Recording devices when I tried to connect it worked for very short time and after this somehow disconnected by itself.
I don't know if I explain well what's happened, but if you want to ask something to make clear, please don't hesitate.

Does your computer have a built in bluetooth as if not you need to use the dongle that came with the headset. Also make sure the required services are running (Start, Run and type services.msc and make sure both Bluetooth Support Service and Handsfree Headset Service are running and make sure in your sound properties to set the headset as default
