I do have the Asus Rampage II Extreme Motherboard, Windows 8, 64-Bit and bought a new headset with a bluetooth-adapter included. When I plug the USB-adapter on my system it works fine.
After wake up my system from the standby-modus, Windows Device-Manager detects a problem with the adapter. The headset don't work anymore. I do have to unplug and plug again the adapter, then everything is ok.
What I have done already:
- Have the newest BIOS
- Installed Intel Chipset 188.8.131.526
- Disabled all USB-Root-Hub to prevent the system to disabled devices to save energy
- Disabled settings for selective USB-save energy (Windows Energy options)
