1.`GET_DESCRIPTOR Configuration`, see the section on [Handling GET_DESCRIPTOR Configuration Requests](./get-descriptor-config.md#handling-get_descriptor-configuration-requests)
2.`SET_CONFIGURATION`, see the section on [SET_CONFIGURATION](./getting-device-configured.md#set_configuration) of this course material
The starter `common/usb` code contains unit tests for these other requests as well as extra `Request` variants for these requests. All of them have been commented out using a `#[cfg(TODO)]` attribute which you can remove once you need any new variant or new unit test.
✅ For each green test, extend `usb-4.rs` to handle the new requests your parser is now able to recognize. **Make sure to read the next sections as you're working**, since they contain explanations about the concepts used and needed to complete this task.
Each file contains just enough code to parse the request in its name and the `GET_DESCRIPTOR Device` and `SET_ADDRESS` requests. So you can refer to `solution-get-descriptor-configuration.rs` without getting "spoiled" about how to parse the `SET_CONFIGURATION` request.
