My desktop's Windows 7 installation was working perfectly but recently I ran into a problem where it would not come out of sleep. The system seems to be running it's just that it won't come out of the sleep state. If I have to guess I would say that it's not recognizing the USB and thus not waking.
I'd say this was a standard problem with Windows not sleeping/hibernating properly, but it was working fine for about a year and stopped working around two weeks ago.
I have hybrid sleep ON and USB selective suspend ON.

I had the same problem, and also frequently freeze.
IF YOU GOT ATI
Solved like that:
Go to \Local Settings\Application Data\ATI\ACE\Profiles.xml and replace "x" by "X"
The problem is due to the powerloss of the ATI devices when it go to sleep mode. This will adjust the power !
ELSE I DON'T KNOW ! =)
