How to dynamically install/uninstall filter driver

NTDEV
1

Hello All:

There is a utility in NTDDK: USBVerify, but it doesn’t provide source
code.

Does anybody know how USBVerify implements to dynamically install/uninstall
its filter driver for each device. Or, does anyone know where to get the
source code of USBVerify from other resources except NTDDK.

Thanks in advance for your help!

Regards,
Shunnian

There is no magic. It stops the device, adds the UpperFilters registry
value to the devnode registry (using SetupDiSetDeviceRegistryProperty)
and restarts the device.
