I was having a Bluetooth problem and after talking to an Applecare tech, I learned the following... If you have an "incompatible" USB device attached and the computer is shut down, upon restart you will have no Bluetooth capability. See: http://search.info.apple.com/?search=Go&lr=lang_en&kword=&q=300429 and http://search.info.apple.com/?search=Go&lr=lang_en&kword=&q=86496 The immediate solution is to unplug the incompatible device, unplug the computer power cord for about a minute and restart. What makes the device incompatible is not addressed. If it is plugged back in, it will work as a USB device, but if you shut down with it connected, and restart, the Bluetooth module is not recognized. Raymond P Reedy popreedy at comcast.net
