Why was my bluetooth card not recognized?
I turned on my MacBook and my Bluetooth was not recognized by the OS. I had to shutdown and restart until it was finally recognized. Could this be a hardware malfunction waiting to happen?
Are you running Snow Leopard? It happened to me once as well not long after I did a clean install of Snow Leopard on my C2D Macbook. A reboot fixed it for me. There's a thread about people having the same problem and some of them have had to reset the SMC/PRAM to get Bluetooth back: http://discussions.apple.com/thread.jspa...
