Suspend and Wake up interrupt

I have a 6410 friendly arm board. I wrote a driver that determine EINT0 as
wake up source. When I suspend windows CE, mouse and keyboard hanged. After
some minutes delay, the Windows CE suspend and LCD become off. Also when I
activate the EINT0, the windows CE come back, But all USB devices such as
mouse, keyboard, and also touch LCD and other devices not work. Also, the
ActiveSync doesn't work. What is the problem? what must I do to correct
this problem?

I make a mistake. The backlight became off. I suspected, it became suspend.
I write a driver that determine EINT0 as wake up source using
IOCTL_HAL_ENABLE_WAKE. But it isn't working. I can't wake up Windows CE
from suspend mode. What must I do?

Does anyone could suspended 6410 and then it waked up ?

Pin 89, S7 Button is determined as wake up source. But in my board it
doesn't work. I don't know why?
