i just recently bought a billionton bluetooth dongle and when i tried to search it for other bluetooth devices, it just keeps on searching and end up not searching anything. i set my other devices at discoverable mode but it still to no avail. is this dongle defective?

I have three bluetooth-capable devices TT2, HBH-60 and T68i but none of them was discovered by this freakin dongle! im getting disappointed with this and its about to be RMAed!
