Quick question. I have two cheepo USB Bluetooth adapters for my Windows 7 PC. One is a tiny generic (thumbnail sized) micro adapter, the other a small "stick" made by Rocketfish. Both adapters install and "claim" to detect my Bluetooth speaker (misidentifying it as a Bluetooth headset. I have no headset), but the speaker doesn't detect the PC (even when clicking the Discover button.) My cellphone sees my speaker, but it too DOESN'T see my PC. Are all Bluetooth adapters the same and if my cheap adapters won't pair with anything, neither will an expensive one? Or might there be something else going on? Thx.
