Joypad detection ... ?

I have a xbox 360 controller and it shuts itself off. If the controller is 'on' when the game loads, it is detected. But if it is 'off', then even if I turn it 'on' after the game has started it is not detected.. Is there away to force the engine to recheck for a connected controller? I did look at the manual and didn't find a way. I would like to be sure I can't do it before asking the developers to add this. ( I sometime jump the gun in the future section)

Thank you for any replies.

Ah thank you for the reminder, I wanted to ask for this feature as well, but please go ahead and do so!
Currently, this is only possible if you use some separate (Windows?) functions, JibbSmart has done this before for his KarBOOM game.

Thanks Superku. Posting to 'Future' now, will link here.
