You could implement the requests as per the USB specification once the hub binds to the generic hub driver. We dont have any example applications that issue any of these requests, please refer to a code from Github if you would like a reference on how the commands are passed.
Thanks for the information. How is Cypress testing this functionality to
demonstrate the CY7C65631's compliance with USB 2.0?

The compliance tests carried out for the hub are per USB 2.0 Hub class specification and the compliance tool issues all the required requests. Since our hub is compliant with the USB 2.0 specification (TID# 30000060), it means it has passed all the tests from the compliance test tools.
