If you declared output reports for your mouse then you are out of luck.
The output reports are written with WriteFile, but Windows opens the
mouse with an exclusive CreateFile call denying all other CreateFile
calls with read or write access.
Try declaring feature reports.
HidD_SetFeature happily works on a file handle opened WITHOUT read or
write access.

i use HID Descript tool (DT.exe), use the mouse sample , modify to my
HID mouse description.

then i use DDK\src\wdm\hid\hclient tool, call HidP_SetButtons /
HidP_GetButtons, Write/Read data to my HID mouse, it's return
success...

now , i have a problem........ =.=||
how could i get then Write/Read event in my HID mouse driver,
(DDK + DriverWorks, i use vhidmou sample under XP)

i trace message by DriverMonitor, i can't got any message in
ReadRepoort() / WriteReport(), (just got ReadReport() message, 1~2
times when driver start)

how to get R/W MESSAGE ????

No wonder these functions succeed. They only fill the report which you
will have to write with writeFile, only that WriteFile cannot work on a
mouse.

As i said the problem lies with Windows and standard file security. The
device has been opened exclusively with a CreateFile call by Windows.
All other CreateFile calls for read or write access fail.
You can either define feature reports or declare a second top level
collection which shows up as another device. Make that a generic HID and
you can gain access.
