@ -37,7 +37,7 @@ To handle a SET_CONFIGURATION, do the following:
- if `wValue` is non-zero and valid (was previously reported in a configuration descriptor) then move to the `Configured` state with the new configuration value
- if `wValue` is not valid then stall the endpoint
In all the cases where you did not stall the endpoint (by returning `Err`) you'll need to acknowledge the request by starting a STATUS stage.
In all the cases where you did not stall the endpoint (by returning `Err`) you'll need to acknowledge the request by starting a STATUS stage.
This is done by writing 1 to the TASKS_EP0STATUS register.
NOTE: On Windows, you may get a `GET_STATUS` request *before* the `SET_CONFIGURATION` request and although you *should* respond to it, stalling the `GET_STATUS` request seems sufficient to get the device to the `Configured` state.

Note that these logs are from a Linux host where a `SET_CONFIGURATION` request is sent after the `SET_ADDRESS` request. On other OSes you may not get that request before the bus goes idle. Also note that there are some `GET_DESCRIPTOR DeviceQualifier` requests in this case; you do not need to parse them in the `usb` crate as they'll be rejected (stalled) anyways.

At this point you can double check that the enumeration works by running the [`usb-list` tool](#listing-usb-devices) while `usb-4.rs` is running.

Both the J-Link and the nRF52840 should appear in the list.
You can find a working solution up to this point in `src/bin/usb-4-solution.rs`. Note that the solution uses the `usb2` crate to parse SETUP packets and that crate supports parsing all standard requests.
