Why wont my bluetooth adapter connect to my phone or headset.?

My buddy gave me an EDR Class 1 bluetooth adapter a few months ago, and i just now got to try it. i hooked it up, installed the onboard drivers, and it said it was functioning. well i tried to connect my emerson headset, using windows to discover devices, and it wouldnt find it. when scanning with my enV Touch, i found it, but it wont connect.
