Dear All,
I have a pointer port pnp driver which layers under mouclass. Now i
need my driver to respond to user ioctls. So i expose a symbolic link for my
device object. Now the problem is, whatever ioctls’ are sent to my device
are getting filtered by mouclass.sys.
Now i thought of creating a dummy device for each actual device so
that the dummy device will not be on the stack of mouclass and can respond
to IOCTl’s. But this method is becoming hectic.
Can someone suggest me a more elegant method…
cheers
Sesha.

Why do you need to create dummy device for EVERY one of the actual devices ?
You could use just one.
