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 USB "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 (both are in Discover mode.) My cellphone however sees the speaker just fine, but it too DOESN'T see my PC. Are all Bluetooth adapters the same? And if my cheap adapters won't pair with anything, will an expensive one? Is this a known issue or might there be something else going on?
