Sleep() issue

Hi,

In my program I need to wait for a device for about 2ms. The accuracy of the
wait is not critical.
It works under Windos XP with a simple Sleep(2).
Under XPE the same program will wait for 15ms instead of 2ms.
Any value for Sleep() lower than 15ms will produce the same wait of 15ms.
The use of SetWaitableTimer produces the same effect.
How can I get a delai of few milliseconds in XPE?

Thanks
Senen
