Bluetooth dongle problem

Hello I have been struggling this problem. It was working without issue before but now when I plugged my cheap bluetooth 2.0 dongle it has some errors. Tried to force drivers myself but I couldn't find Generic Bluetooth drivers. It was there before but now it has gone and also tried installing different drivers still no luck. Plugged different ports and tried different dongles still same. Is there any way for make this dongle work again? Thank you!

How much is your time worth? Bluetooth dongles can be purchased on-line for very little money. Personally, I value my time enough that I would not spend much of it trying to get that old one to work, I would buy another and move on.

I have 3 bluetooth dongle devices which all was working properly before. The point isn't money, dongles wont work something wrong with my pc. Now on device management dongle manufacturer says Realtek, it was cambridge silicone radio before. Something messed up.
