I just bought this USB adapter to use on my iBook, which it works fine. I want my mouse or my keyboard to wake up when asleep. But the Allow Bluetooth device to wake this computer is grayed out. Any reason why that is. Sorry for the double post but I thought I would get more replies here. Also does any one know if the D-link 120 does the same thing or should I just throw out the kensington and buy a dlink one
