Driver prevent S1 standby but aloow S3 standby ?

Hi,

Our device driver is a USB port driver sitting below a mouse class
driver.
I found if I set the BIOS option "Suspend to RAM enabled (S3)".. WinXP
is able to go to standby with our deivce attached.
While if BIOS option "Suspend to RAM disabled(S1)".. system would claim
that our driver prevent the system going to standby..
The following is a bit of debug info...

I found our driver return success for Query Power,, but system just set
the device to D0..when S1 .. ,, (while it would set device to D3 when
S3 Query..)
Any hint for that ?

Thanks.
