Response
If the command cannot be processed, the device stalls endpoint 0. The command cannot
be processed if the memory area is not valid. It cannot be processed if the request is
attempting to access data that is outside the specified memory area. This may happen if
the index is too large or too much data has been requested.
The host can send a status request, as long as the endpoint is not stalled, to determine if
this request was executed properly.
