I have a Sony DR-BT101 bluetooth headset that I have used for a long time under Windows 7. I recently bought my MBP 15" and successfully used the headset under Snow Leopard and under Bootcamp with Windows 7 installed. Now after updating to Lion, the headset still works when using OS X but will not work when using the same Bootcamp Windows 7 partition. It seems to try and find drivers which do not exist for this device. I get a momentary indication that everything is working and then Windows says the drivers were NOT installed. Anyone experiencing this kind of problem? P.S. I already have a call into Apple tech support.
