Why? The bus driver owns these devices. You can’t force it to cede control of them, and if you did it would just re-enumerate them. Tell us what your REAL goal is.

You need to write a bus filter.

Now, as Mr. Roberts ask, please tell us what you’re trying to accomplish, using more than two sentences.

Actually i have written usb bus filter driver, which is monitoring USB devices. so i need to prevent attachment as well as detach connected devices(USB device PDO should be deleted). Right now i have done code for prevent USB devices. But i need to know how can i detach connected device.
