Hi,
I have created a Driver named \Driver\mydriver.sys in my code. But while trying to track IRP calls I am getting

“Device Selection Failed - GetLastError returned 123”

Please Help me in suggesting me how to track IRPs of a Driver.
Any help will be appreciated.

this message/what is showing you this message?
