Phew! Glad I found this post! I thought my Azurewave card was faulty when BT stopped working between OS X and Windows, but it seems it were driver issues then.
I reinstalled OS X and put your kext, worked at next boot.
I still have one issue. I am using a Magic Mouse, and when I put the system to sleep, it wakes up a few seconds later because of the Bluetooth device.
Here's the console entry:
The USB device BCM20702A0 (Port 7 of Hub at 0x14000000) may have caused a wake by issuing a remote wakeup (2)
Any way to solve this?
Also, I may add that the console entry says BCM20702A0, but in System Profiler it appears as 20702A3, don't know if that affects...
Thank you!!!!
