 When the host issues a GET_DESCRIPTOR *Configuration* request the device needs to respond with the requested configuration descriptor *plus* all the interface and endpoint descriptors associated to that configuration descriptor during the DATA stage.
 
- A GET_DESCRIPTOR Configuration request is a GET_DESCRIPTOR request where the descriptor type encoded in the high bit of `wValue` is CONFIGURATION.
+As a reminder, all GET_DESCRIPTOR request types are share the following properties:
 
-Let's look into all the concepts required to respond to this request.
+- `bmRequestType` is **0b10000000**
+- `bRequest` is **6** (i.e. the GET_DESCRIPTOR Request Code, defined in table 9-4 of the [USB specification][usb_spec])

+
+A GET_DESCRIPTOR *Configuration* request is determined the high bit of its `wValue` field:
+
+- The high bit of `wValue` is **2** (i.e. the `CONFIGURATION` descriptor type, defined in table 9-5 of the [USB specification][usb_spec])
