Hi, all!

I am writing a FS filter driver. I want to send IRPs to USB filter driver, but I don’t know
how to send IRPs to USB?

Can someone help me? Thanks in advance!

No one answered your question the last time you ask this. Why do you
think it will be different this time?

You simply dont give enough information to answer your question.

What IRP are you trying to send? Is it your USB driver?

Explain what you are trying to do in more detail and people may try and
help.

Thanks Tony!

In fact, I just want to send some special info to my USB device. While my driver is upper the FSD, so it seems that I have to send IRPs to USB driver. But I don’t know whether all the IRPs sent to USB driver can be sent to my USB device or nnt? Should I create some special packets?

Try using device control calls to your device then. That’s the “escape”
mechanism that allows you to call with whatever private protocol you
wish to develop.
