Hello All,
I want to develop a USB Filter driver which will sit below all USB function drivers. This filter driver should get all the IRPs independent of USB device plugged in USB Port. and I need to pass all the IRPs to a different system through TCP/IP. I need this on Windows XP.
My question is:
1) Does my Filter driver should be below function drivers or below the USB HUB driver?
2) Is it possible to send the IRPs received in filter driver to send through TCP/IP? Do i need to develop any additonal application to do this?
3) Is there any sample where i can start off?
If any of you guys had a similiar request please help me?
Thanks & Regards,
James.

service keys aren’t for devices. service keys are for drivers.
You have a device hardware key and a class key, but that device can have
multiple drivers installed. You would need to query all of the drivers
running on the device (service, upper and lower device filters & upper
and lower class filters) and then open
HKLM\System\CurrentControlSet\Services<service_name>
What are you hoping to do with the service key? Perhaps you don’t need
it after all.

Setup api has functions to let you query the properties of the device
node (setupdiquerydeviceregistryproperty maybe - I don’t have a DDK
here). You can query for the driver lists that I mentioned below.;
