Have you tried reconfiguring the power saving settings while the 
controller is connected?

It is possible that the device prevents the system from entering a reduced  
power state, in which case the problem is not limited to just the display.  
Note that the hard drives are controlled by separate timers.

One thing to try is updating to newer drivers (if available), both for the  
device itself and for the USB controller (i.e. chipset drivers).

If on Vista, make sure to enable "USB selective suspend" in the power  
management options.

If on XP, there is a hotfix that may or may not help.

  It's a bad idea to put relevant information *after* your signature.

  Many newsreaders will color signatures differently from the rest of
the post, and this causes natural signature blindness to people, and
they will miss your relevant info.

That saves much more power than letting it turn off automatically. 
However, see PPPS on his post.

If you find a way to make anything in Windows behave the way it should, 
come back to us.  Inquiring minds want to know.

I tried the hotfix, and no go - it still won't sleep.  Thanks for the 
tip, though.

If you're using Vista there's a known problem with some wireless USB  
devices disabling the screensaver (and by extension perhaps the power  
saving) http://support.microsoft.com/kb/911895 had the same thing happen  
on a laptop and after a couple of reboots seems to be working properly  
now. Might be worth a try. Oh and the device needs to be plugged in before  
it shows up in the Update screen.

It is behaving as it should. The game controller device driver is 
telling Windows not to stop supplying power to it. So Windows does what 
it should.

Now, if the game controller doesn't have problems with going into 
low-power mode, then it should let Windows do that. Blame the controller.

No, the game controller is preventing my monitor from going to sleep, 
even when the controller isn't being used!

I'd say that it's not functioning how it should :/

The controller is in some sense being used as long as it's plugged in.

Right. The *controller* should be built to not as Windows to do that. It 
isn't Windows doing something wrong, it's the controller.

If the controller is powered by the USB and says "don't remove power", 
then yes, Windows isn't going to power down.
