Bluetooth USB Dongle Stopped Working

Vista Home Premium

I have a D-Link DBT-120 USB Bluetooth Dongle that has been working fine. All
of a sudden it has stopped working. If I access the Bluetooth Control Panel
Icon is seems not to exists.

If I plug it into another USB port it recognizes it and says the drivers are
installed but does not work.

I have tried it in another Vista Computer and it works fine.

I have tried another USB Bluetooth Dongle (a BlueSoleil one) and this does
not work either. I have tried to uninstall it and rebooted to try and get it
re detected but still no go.

Any ideas?
