It is tricky and I am not willing to go back to the per connection link policy setup, because that interferes with how with setup Bluetooth 2.1 devices. Problem is that this particular firmware is a custom build for Logitech (or beta firmware) as it looks like. Also you have other problems with not having AFH enabled when you have WiFi around. I think that I do have the exact same mouse and keyboard at home somewhere. But not supporting Default Link Policy is just pure stupid. Regards Marcel
