I've got an magic mouse and an apple bluetooth keyboard.

I usually run ubuntu on my computer, but sometimes I need to use windows 7 from an external disk.

Whenever I boot into the other system I have to pair my devices again.

Is there a way to make this work? I've already tried setting the hostname to be the same, but this didn't work.

Probably you've already found an answer. But for the sake of completeness here is the link where it is explained http://ubuntuforums.org/showpost.php?p=9363229&postcount=5 . The pin code used for pairing is used to generate a another key. This key is different even each time for the same pin. That is why same pin does not work. You have to copy the key from WIndows to Ubuntu machine.

Every time you load an operating system, that OS needs to load the hardware drivers. Even if you are loading from hibernation, it still loads/refreshes the drivers again. Try it... uninstall a driver in Device Manager, and immediately hibernate. When you restore from hibernation, the driver is there in Device Manager again as if you had restarted.

You need to pair the bluetooth devices after the drivers have been loaded.

The only way to keep the bluetooth devices connected, is to keep the bluetooth receivers active. The only way to keep them active, is to not unload them from the system. The only way to not unload them from the system, is not to shut down the operating system that is accessing them.

Now, if you were running one of the operating systems in a virtual machine, that's a whole different ball game. But since you are not, and since you actually reboot between changes, then no. There is no way with your current usage choices to make the bluetooth devices avoid having to be re-paired each time.

I'm not sure we're talking about the same thing. If I reboot the system I don't have to re-pair the devices, they connect automatically. If I, however, switch the operation system, they aren't able to connect automatically. –  Georg Schölly May 9 '12 at 14:49
