Voyager Legend has lost connection with USB dongle

[KrisKK]

Hi, my USB dongle has lost connection with headset somehow. When I plug in the dongle it starts flashing for some time and lights off. However OS "thinks" that it works, while it is detected normally. A headset doesn't inform about connection with PC as usual was. Is there any re-pair procedure available?

So i found the procedure how to pair headset with dongle. I did it and it works again. Why it was un-paired is mistery.
