No, don’t think so. I’m also curious to see what the stack looks like, however if you are the highest upper filter in the stack I don’t see how you could miss any I/O from user mode.
From looking at device tree I noticed that each device is associated
with an unnamed and named device. My filter driver is installed on the
unnamed device instead of the named device. What do I need to do so that
my filter gets installed on the named device?

Your question is unclear. PDOs have names , FDOs do not. Are you saying that you placed your filter between the PDO and FDO instead of on top of the FDO?
