USBFN => data abort in Windows Embedded CE6.0

Hi, how are u?

Previously I made a question about 'Data Abort' in Usbfn pdd device
driver.
But, I tested several times with the other souce code, Sc2440pdd.cpp
file for WinEmbCE6.0.
This code already has been confirmed by the reference board made by
MDS technology which is one of embedded software company.

So, with this confirmed source code Sc2440pdd.cpp, I tried to adapt to
my WinEmbCE6.0 BSP project.
But error has happed like below.

error has been happened just after finishing calling UfnPdd_IOControl
function.
and the parameter of UfnPdd_IOControl is wired.
(with WinCE5.0 there is no calling this function with this parameter)

....
OEMInit: KITLIoctl end

Recently, I really made lots of questions at this place.
Because I think you are very good at WinCE over the world.
Thanx for your help in advance.
