- Store configuration index in the setup packet
- Perform retrieving the configuration request before storing the configuration details. Perform the same action for the select interface request
- EHCI now supports selecting configuration & interface on devices with more than one configuration (previously only one configuration was supported)
- Code has not yet been tested, as no available usb device has such feature
