An alternative might be to fail all IO until you get the ‘enable’ IOCTL on your control device

That window is very small since the only way your driver can load as a pnp driver is when the pnp device shows up. That means driverentry will be immediately followed by AddDevice, I doubt your app can even hit that window in between. And how will it know when the symlink is available?

Hi Doron,
Thank you for reply. But what if I want to send IOCTL to my driver before any device has added, what is the approach in this case?
