Recently my Windows 7 64-bit has found an unknown device in the category of USB controllers. It was not able to find any driver neither on my computer, nor on Windows Update servers. At the same time Bluetooth support and device disappeared.
Simple logic suggests that somehow Windows has lost information about Bluetooth driver and now recognizes it as unknown USB device. Moreover, afaik my internal Bluetooth is connected through USB interface to the main board.
Any suggestions? What should I do to diagnose the problem? How do I fix my Bluetooth w/o reinstalling Windows?
Hardware: MacBook Pro 15" (6.2, mid 2010).
