Hello,
When i tried to uninstall upper filter driver it also brought down the pdo
driver? Why it happened?

Do i need to forward all all minor PNP function down to attached driver?

Thank you
Alex

Yes, when you make a pnp change the entire stack is torn down and rebuilt. Any reason you are not using kmdf? It handles all of the pnp and power things for you

Hi
I never used it before.
Can you point me where i can find more details about kmdf?

I looked in kmdf/filter/generic and compiled it. It creates inf file. Should i need to update it (replace toaster name with name of driver that i’m filtering?

Thank you
Alex

That you are new to kmdf notwithstanding, it is so the way to go, in my opinion.

Good luck,
